Wine doesn't support 5.1 and 7.1 sound

[Id2ndR]

Binary package hint: wine

Wine currently only support stereo sound. It would be great to have more channels and get 4.0, 5.1 or more.

[Benjamin Hodgetts (enverex)]

Pretty sure Starcraft doesn't have support for actual multi-channel surround. If anything it may support "Dolby Pro Logic" or "Dolby Surround" neither of which are actual surround sound and don't require anything other than stereo from your soundcard (Pro Logic is decoded by a HiFi or amp that has that ability). Basically they are all "fake" surround.

Yeah, just checked, it's "Dolby Surround". There's nothing Wine needs to do to support this, it's already working, you just don't have the correct hardware connected to your PC.

[Benjamin Hodgetts (enverex)]

Amazingly this bug doesn't seem to have been filed before (support request for multi-channel audio) so correcting the details to make more sense. This isn't likely to be done for a while thought due to a) drivers not being that great, b) EAX missing entirely from drivers and other reasons which I'm sure the devs can give you.

[Rbrandonstewart (rbrandonstewart)]

It is my understanding that EAX (Environmental Audio Extensions) and surround support for DirectSound are two independent things. EAX is just a bunch of environmental audio presets, and has nothing to do with hearing enemies coming from behind you in 3d games.

I can select 5.1 audio output in Team Fortress 2, but there is no audio from the rear speakers and when I restart the game the sound option is reset to stereo.

It would be wonderfull to hear full 5.1 or 7.1 sound in games such as World of
Warcraft, Guild Wars or any other game (3D shooter for example) that allows
multichannel sound output. Difference between how those games sound in Windows
and Wine is MASSIVE.

[Iuga Marian Silviu (iugamarian)]

And there is a game that has a problem with sound in wine.
Please get this game from http://www.iuga.go.ro/bile.exe
and make it work on newer versions of wine.
The problem consists in that when a ball is moved on a
wider path, the bumps of each jump are not all heard,
and also, when a row of balls dissapears, the boom
sound is heard only about at 50 % chance.
Thanks in advance.

Is there any news regarding this.
Is it possible to somehow use 5.1 or any other multi-channel sound by now?

Still unimplemented, but with Maarten's recent work with Wine and OpenAL, it's much closer.

But the sound sources of OpenAL are usually mono.

Thank you for posting this bug.

What version of Ubuntu & WINE were you using?

Does this occur in newest WINE?

[Adam Bolte (boltronics)]

I've spent most of today looking into this. All testing was against wine 1.3.10.

My system uses a Gigabyte X58A-UD9 MB with on-board Realtek ALC889 sound connected to a Logitech Z-5500 5.1 system via analogue, and I'm running Ubuntu 10.04.

Under the Sound Preferences Hardware tab, I have selected "Analog Surround 5.1 Output".

When I run the command “speaker-test -c6 -l1 -twav” everything plays exactly as expected. I've also added the following line to my /etc/pulse/daemon.conf file to disable channel remixing:

enable-remixing = no

Otherwise it's not always immediately obvious if games are actually supporting multi-channel or not. Additionally, my bare-bones ALSA config file redirects everything to PulseAudio by default.

I've mostly tested games with ALSA selected in winecfg, but tried a couple of games with the WinePulse patches and using PulseAudio directly to see if it made a difference. It didn't.

The results:

In Portal, selecting 5.1 reverts back to stereo after freezing for a few seconds. Selecting a multi-channel sound configuration is not possible (sounds like the Team Fortress 2 report above).

StarCraft 1 certainly didn't output anything to my rear channels, as expected from previous comments here.

StarCraft II, looked promising (I can select 5.1 from the drop-down successfully) but it actually seems to do nothing (no audio was heard from the rear channels). I tested as much as the menus and game cut-scenes.

UT2004 and Killing Floor (a UT2004-based game) also didn't run multi-channel, even after adjusting some of the audio settings in-game.

Aliens Vs Predator was only stereo, and doesn't provide an option to tweak anything useful audio-related in-game.

Despite all these failures, Unreal Tournament 3 multi-channel audio actually worked effortlessly. You can clearly hear menu click sound effects in the rear speakers, and surround sound in-game appears to work perfectly (I played a few matches to test it out – using the patch for bug 6971 of course).

Given that UT3 worked, I tried Stranglehold (UT3-based), but that *didn't* work. There wasn't much in the way of in-game options there. Perhaps if I had more time I could try diff'ing the UT*.ini and Stranglehold ini files... don't know.

I've got plenty of other games I could try, but that's it for now. Very curious to know what's so special about UT3. Either way, it would be awesome to improve multi-channel sound compatibility. I personally don't care about EAX.

[Raymond (superquad-vortex2)]

wine need to implement dsound 's speaker-configuration to find out your speaker arrangement is 2.0 , 4.0 , 5.1 and 7.1 from Sound Preference and use alsa's analog front , surround40, surround51 and surround71 devices, iec958 for digital audio pass through coxial/spdif to your digital receiver, hdmi for your hdtv or hdmi receiver

This is easy for desktop with 6 audio jacks in rear panel since you don't need to change the switches of your sound card (e.g. "Smart51", "Channel mode" to retask the pink and blue jacks as output

[Adam Bolte (boltronics)]

I don't think I've ever used a sound card that required retasking the input jacks as outputs for additional channel outputs, but would assume it would entirely be taken care of in ALSA.

I suspect (as far as Windows software goes) only driver utility software would need this functionality, and WINE in general doesn't deal with drivers. Thus, I figure we only need to work with whatever is already configured in ALSA/Sound Preferences and keep things simple? Hope I understood you correctly.

[Raymond (superquad-vortex2)]

Those are motherboard with only 3 audio jacks at rear panel

Take a look at videos

For example, you can listen to one audio source through the back panel speakers and a second audio source through front panel headphones or speakers.

Doesn't UT3 use OpenAL?

[Adam Bolte (boltronics)]

Thanks Raymond.

> Doesn't UT3 use OpenAL?
Just took a look at the OpenAL WikiPedia page, and it does. So does UT2004 though, but that didn't work.

I noticed BioShock was on the list, so I tried a BioShock demo I downloaded ages ago. It had an option for 5.1... looked promising, but again no success. Tried restarting the app, noticed 5.1 was still selected, but still no multi-channel. Must be something else that's special about UT3...

[Raymond (superquad-vortex2)]

according to the pdf , second audio source through front panel headphones can be accessed through dsound

does your snd-hda-intel provide this independent headphone device ?

[Adam Bolte (boltronics)]

I have no idea. I suppose I would have to load up Windows and hunt around to see if it's possible. I know the Windows configuration software that came with my motherboard doesn't look quite like the one in the picture.

Definitely under PulseAudio I can tell Xine to play to iec958 (eg. Dolby Digital DVD audio via passthrough) simultaneously to, say, having mplayer play a flac file to analogue-out channels... but I assume that's not useful to you - I think you want to know if it's possible exclusively using my front and back analogue jacks. I might get a chance to try it tomorrow night.

[Raymond (superquad-vortex2)]

The "Multistreaming" option of realtek and idt codec is similar to the "Independent Headphone" switch in snd-hda-intel if you are using VIA HDA Codec

Multistreaming under Windows

Windows 7 multistreaming via Realtek ALC889, as found on a Gigabyte X58A-UD9 motherboard.

[Adam Bolte (boltronics)]

As per the image attached above, I discovered that multistreaming on my motherboard is possible under Windows 7. The options only became available when I had the headphones physically connected. However, I have yet to figure out any way to achieve the same thing under my Ubuntu 10.04 system. I've been messing around with it and searching for hours without success.

I did notice in alsamixer a Headphone option. If I connect headphones to the front of my case and leave that box ticked while playing audio in mplayer, I get the same audio stream simultaneously sent to both my front speakers and my headphones.

If I leave headphones enabled but mute the front speaker channel, both stop working. If I untick the headphone checkbox, both the headphones and front speaker channel also stop working. It certainly looks like these are both sharing the same channel, and I can't see any possible way I could redirect audio to one specific set of speakers. This is all aplay shows (aside from some other "surroundXX" plugs that seem unlikely to be useful):

$ aplay -L

Would attaching anything else in particular be useful?

[Raymond (superquad-vortex2)]

alsa seem only implement the capture devices only

do you have additional capture device (hw:0,2) ?

arecord -l

Take a look at block diagram of alc889 datasheet and the codec-info section in the output of alsa-info.sh

Ten DAC channels support 16/20/24-bit PCM format for 7.1 sound playback, plus 2 channels of
concurrent independent stereo sound output (multiple streaming) through the front panel output

The "6stack" or "6stack-dig" model connected both HP and Line Out (Green) to the front channel [Audio Output].

you need to implement a new model "6stack-dig-fronthp" which connect your alc889's alt_dac_nid 0x25 to HP out at Ext Front and modify the driver to create stream_analog_alt_playback (device 2) and create the volume control/switches

I appreciate your help, but don't fully understand the situation. Why does WINE need to get multistream functionality working, when a model in ALSA with that support doesn't appear to exist? I would have figured nobody could use such functionality yet, so it wouldn't be useful for WINE to try. UT3 works, and personally I've never actually used the front HP port before looking at this bug either - 3.5mm headphones plug into the receiver.

I would be very happy to test any patches though, if you feel up to it.

Alsa works very well with multi-channel. I would take a look at the alsa sources for this alsa program that works out of the box:

speaker-test

I am not a c/c++ programmer so I leave it to you.

[Adam Bolte (boltronics)]

(In reply to comment #27)
> Alsa works very well with multi-channel.

Nobody has said otherwise. multi-channel != multistreaming, and multistreaming is already possible if you have multiple output devices (which I previously mentioned). Raymond is talking about multistreaming between the read analog and front analog ports of the same device through ALSA, which doesn't seem to be supported.

I'm not sure why getting this sorted out is a requirement to get multi-channel working but I'm not a WINE programmer.

ALSA require sound card to use "surround40" , "surround51" to play multi-channels

it is ok if you are using the onboard HDA with 6 audio jacks in rear panel

if you look at the above URL of intel desktop audio support

when your Micro ATX motherboard only has three audio jacks
you need to configure Configuring 6-Channel Audio and retask "Mic" and "line" for output

Item Description
A Line In [retaskable as Rear Left/Right Out]
B Line Out [Front Left/Right Out]
C Mic In [retaskable as Center/LFE (Subwoofer) Out]

the other sound cards may need to change the "channel mode" from "2" to "6" and that switch is hooked with the "surround51" device in /usr/share/alsa/cards/*.conf

but winealsa does not use those devices name

There is Accelerated ALSA Library for Linux for emu10k1

and

Configuring Surround sound in Linux if you are using openal

[Adam Bolte (boltronics)]

> you need to setup the parameters in .alsoftrc for those openal games if you are

I certainly did that, and I've tried various configurations. I must have got it correct if it works in UT3. Surround also works in native games like Doom 3, Quake 4, and Prey. I even get rear speaker channel audio in the oldies Majesty and Return to Castle Wolfenstein.

As an additional test to the games above, I just tried Wolfenstein under WINE. No surround there either, unfortunately (even though it's another OpenAL game).

As for the hardware-accelerated emu10k1 driver:
http://frictionalgames.com/forum/thread-3490.html

Both Urkle (from the forum thread) and yourself are probably both referring to the project here (last updated 2004!):
http://www.lost.org.uk/openal.html

[Raymond (superquad-vortex2)]

That accelerated alsa driver for emu10k1 only provide stereo control of those hardware mixing volume controls provided by snd-emu10k1 similar to

http://git.alsa-project.org/?p=alsa-tools.git;a=blob;f=hwmixvolume/hwmixvolume

It actually playback different openal mono source through different subdevices instead of mixing those mono sources by openal

That implementation is the basis if winealsa want to provide dsound hardware secondary buffers for ds3d

you will need to enhance the openal-alsa-emu10k1 to control the rear speakers since the volume of the rear speakers is controlled by another sets of "EMU10K1 PCM Volume" , "EMU10K1 PCM Send Route" and "EMU10K1 Send Volume" of the rear device

it the application does not provide 6 channels (e.g. openal only pan the front/rear speaker to provide 3D effect and don't have any signal on Subwoofer

if you want to watch movie 5.1 or DTS , why don't you use those linux media application (e.g. mplayer or vlc )

[Iuga Marian Silviu (iugamarian)]

Applications that have support 5.1 channel support, work only with Wine and I also need because they work better than GNU/Linux applications for a specific task:

-WinampAC3Filter plugin for Winamp (Winamp is the only application that has a decent playlist with perfectly optimized controls imho - I mean I can set the imput plugins to display something like "Artist - Album - string of my choosing.filetype - another string of my choosing")

-older games that rely much on multichannel to inform the player of the position of things all around like: Counter Strike, Star Trek Armada II, Homeworld 1 2, Giants - Citizen Kabuto, Command and Conquer 1 2 3

-take utorrent for example - the programmers use the Wine platform to make sure it will work very well in Windows. Programmers may (imho they already) use Wine to check games for Windows and even compiling them using Wine libraries to make them go faster and smoother and would be very happy to not have to load Windows instead of Wine just to test if multichannel sounds work properly

-I am sure I will have more and more needs to use multichannel in Wine as time passes (for example 3D max Studio or Adobe * - make movies in multichannel and view them without rendering just to check sounds)

Those 3D game work best work with headphone when your sound card support Head Related Transfer Function , Interaural time-delay and interaural level difference

The sound signal arrive at slightly different time/level at your left and right ear when your are wearing a headphone since your left and right ears can determine the location of the sound source from the delay and level difference

if your are using 4 speakers , it will depend on whether the speakers are placed at the desired position (same distance ) and angle ( cross-talk between the speakers ) for your ear to get the same delay/level as same as in the game environment ,

Those 3D game usually use surround40 instead of surround51 unless your sound card (e.g. SB Live! emu10k1) has a treble/base control to boost the bass and specical control reverb , echo using FX chip

I don't know if this the right thread for this, but I think I fixed a bug in the multi-channel code:

The problem was: sound in PES 2010 only partially works: effects work, music and commentator doesn't.

Debugging the problem, I noticed that the "cp_fields" function in dlls/dsound/mixer.c is called with device->pwfx->nChannels == 8 and dsb->pwfx->nChannels == 2. Since the case 6 vs. 2 channels was already in there, I added 8 vs. 2 channels and it worked perfectly. Here's the small patch:

Is wine implement dsound.vxd or dsound WDM ?

since dsound.vxd does not support 8 channels or float

dsound WDM , KMixer is responsible for resampling

I did not delete the example. The file has 5 MB and was not attached when I sent the message. Now I will use a public Ubuntu One link for the example:

http://ubuntuone.com/3O64HW4V1L9LxpFbRwNkqH

The example has sounds of lighting a match on each 5.1 speaker, and a seventh match heard on all speakers.
I succesfully played this in Debian Gnu/Linux on 5.1 speakers only with Amarok with libxine1-ffmpeg installed and in Windows with Winamp having Winamp AC3 Filter plugin.

I thank you for your good work.

This file is not what it appears to be. It's a recording of DTS pass-through over stereo PCM... This stereo wav file contains a bunch of noise that's interpreted as DTS codec audio by a receiver and perhaps sound cards.

This is obvious by opening the file in audacity or other editor. The sound of the match is loud and then fades to quiet, but audacity shows that the audio level for this file is constant(indicating it's not PCM data at all).

There are test files here, I'm just looking at them, now.

ALSA multi-channel support is implemented as of Wine 1.5.11 (d402231e3f148a30ceca15c1223a765f5a388379). The OSS and CoreAudio drivers both "support" multi-channel, but don't try to map the channels correctly.

DSound nearly works, but needs some cleanup with regard to mixing streams with different numbers of channels (5.1->2, or 2->5.1, etc.). Fixing dsound is "on my list," and I think we'll close this bug when dsound's channel handling is fixed.

Please continue to post here for now if you have trouble related to multi-channel audio support. We may split off new bugs for the OSS and CA drivers if they're found to be inadequate.

[Win4hq (win4hq)]

Nice, Andrew! Is there any documentation on how it can be used in the current wine release, or what works and what doesn't? My initial tests with a game didn't yield surround sound, but I guess that might be due to a lack of DirectSound support.

[Andrew Eikum (aeikum)]

There shouldn't be any need to set up Wine to use multi-channel audio. Except in the case of dsound, if an application supports it and your ALSA configuration is set up correctly, it should just work. I had the best results when using PulseAudio, as PA deals with most of the ALSA configuration for you.

After dsound is repaired, I'll do a more thorough investigation of the different setups and try to find what works best. For example, many ALSA configurations define devices like "surround51" or "surround40", which might work better, but would have to be added manually with the ALSAOutputDevices registry key (see <http://wiki.winehq.org/Sound>).

[Win4hq (win4hq)]

Let me know if you want someone to help with testing. I have a surround51 device working in linux applications on an ALSA-only system. (After screwing things up so many times, Pulse is no longer welcome on my computer.) The card is an Audigy2 so I have hardware mixing, which I'm told is unusual for sound cards these days. I also happen to have a wine build environment with a recent git checkout.

FYI, I haven't witnessed working surround sound from wine yet, but then again I've only tried one game. I'm not sure what Windows applications would be likely to work.

[Cheako+winehq (cheako+winehq)]

I'm confused help me out, OSS and CoreAudio can do SS?

AFAICT CoreAudio is only available under OSx, is this the same CoreAudio?

However is seams that ALSA is also supported and can even work with PA(pulseaudio).

I've a strange setup, I've likely described it above. I'm using Spdif to a receiver for all my audio and dmix does not work in this configuration. However PA can make use of the a52 ALSA module to achieve AC3/DTS passthrough. The only drawback is that DVDs and Blu-Ray are unencoded and reencoded, but I havn't noticed an issue on this 6 core box.

Thus I'd like to use PA and currently I've got two options for PA. The winePA driver and the ALSA PA driver.

A test application would be grand!

My Microsoft® LifeCam VX-2000 worked fine and perfectly in wine 1.4 versions but in the wine 1.5 versions it does get detected like in the 1.4 but the sound comes out garbled when I test the voice in WoW.

[Andrew Eikum (aeikum)]

<email address hidden>, please open a new bug and attach a log there with the debug channels mentioned at <http://wiki.winehq.org/Sound>.

[Russian redneck (otaku-8)]

Most of apps (incl. winecfg) produce grunting sound when there's more than 2 channels. But even so Stalker CS (using OpenAL probably) produces clear sound on 5.1 profile. Also Zandronum sounds clear (but with bug #34887) when it uses dsound, but without dsound it grunts too.

[Russian redneck (otaku-8)]

p.s. Xubuntu 13.10, Wine 1.7.6, Audigy

[Forest (foresto)]

Looks like work in this is starting to take shape:
https://www.winehq.org/announce/1.7.34

"Support for surround sound in DirectSound."

I haven't been able to verify that it actually works yet, but it is encouraging.

[Austin English (austinenglish)]

This should be fixed in 1.7.34:

please retest.

[Iuga Marian Silviu (iugamarian)]

Thank you very much for fixing this bug.

[Iuga Marian Silviu (iugamarian)]

Resolved. Fixed.

[Alexandre Julliard (julliard)]

Closing bugs fixed in 1.7.37.

[Andrew Eikum (aeikum)]

Thanks to Mark Harmstone for doing the dsound work. Obviously many commits went into this work, so I'm adding a Fixed By SHA1 that points to where the work was largely finished.
