Bug Description
Binary package hint: pulseaudio
Pulseaudio can't find working alsa sound cards on bootup.
"alsa force-reload" after login remedies the problems until next reboot.
Comments 40,41,42 propose a workaround - disabling sl-modem.

Seems something related again to module-hal-detect. Forcing load-module alsa in default.pa gets back my soundcard.

I've now tried to force load-module module-alsa-sink in default.pa as well
Sound playback is back again, but:

I have the same problem. The only app that seems to avoid it is gnome-mplayer.

I've now tried to connect a USB audio interface to my laptop, and it gets perfectly recognised.
Therefore the issue must be with the internal audio device (which used to work fine up to pulseaudio 1:0.9.16~test5).
Regarding my internal audio device, "cat /proc/asound/cards" returns the following message:
0 [Intel ]: HDA-Intel - HDA Intel
What can I do to get my internal audio device recognised?
Thanks

Update: I've just tested pulseaudio 1:0.9.16~
The internal soundcard (ALC268) is still not recognised.

Does your user have permission via PolicyKit or otherwise to access @audio?
fab (fab-head) wrote : Re: [karmic] pulseaudio: card not found - Null Output | #14 |
I think I've found a temporary workaround (not a solution).
I've opened /etc/pulse/
Before:
### Automatically load driver modules depending on the hardware available
.ifexists module-
load-module module-udev-detect
.else
### Alternatively use the static hardware detection module (for systems that
### lack udev support)
load-module module-detect
.endif
After:
### Automatically load driver modules depending on the hardware available
#.ifexists module-
#load-module module-udev-detect
#.else
### Alternatively use the static hardware detection module (for systems that
### lack udev support)
load-module module-detect
#.endif
Then I killed/restated pulseaudio and now I have audio input/output from the internal audio device.
Still, the Hardware tab under Sound Preferences is empty, as if there was no audio device available.

I've now reverted this to its default.

I suggest everyone reporting problems in this bug should try the version of pulseaudio in the ubuntu-audio-dev PPA if you haven't already.
fab (fab-head) wrote : Re: [karmic] pulseaudio: card not found - Null Output | #18 |
Hi Luke,
I'm actually using the latest version from the Ubuntu Audio Dev team PPA and the issue is still there.

Luke,

Hi,
I have exactly the same problem as you Fab.
-null output
-empty hardware tab
I have already tried everything recommended to you but it still does not work.
Also would like to know if there is chance of getting sound back after downgrading from karmic back to jaunty because in my case problem started after upgrading on karmic.
fab (fab-head) wrote : | #21 |
Hi petera,
As Karmic is still under intense development, I believe it is understandable that we might bump into bugs/regressions. The point in using Karmic now is to help test the system and report all bugs here.
The developers will then do their best to fix all the major issues before the final release (Oct 09).
Therefore it won't be of much help if you overwrite/downgrade your Karmic installation at this stage (You always have the option to install Jaunty as you main/production system on a separate partition and keep testing Karmic at the same time).
Regarding the above mentioned issue, I don't know if this could be of any help, but I forgot to mention that pulseaudio 1:0.9.16~test5 ran fine on Karmic. The problem started only with version 1:0.9.16~test6
Luke Yelavich (themuso) wrote : Re: [Bug 394500] Re: [karmic] pulseaudio: card not found - Null Output | #22 |
Have any of you in this bug also tried to delete the .pulse directory and .pulse-cookie in your home directories and reloading pulse?
fab (fab-head) wrote : Re: [karmic] pulseaudio: card not found - Null Output | #23 |
Yes, I also deleted .pulse and .pulse-cookie then killed and started pulseaudio again with no success.
I'm downloading the latest update from the Ubuntu Audio Dev team PPA right now.
I'll let you know the result in some minutes.

Well, this is up to you.
But tell me just one thing: why do you bother testing an OS which is still
under development if you are not ready to deal with some (hopefully)
temporary issues/bugs?
If you want a stable system, please stick to Jaunty until the final version
of Karmic is released.

Hi Ubuntu Audio Team,
Is there any news on this bug?
It would be good to have the internal audio device recognised by pulseaudio on this HP laptop (and potentially on many other notebooks out there).
New users will easily be put off by not having any sound out-of-the-box when they install the final version of Karmic.
Just to recap:
- Pulseaudio 1:0.9.16 test6 and test7: the internal audio device on an HP laptop (DV9850EL) is not recognised and therefore pulseaudio doesn't show any input/output audio device = No audio playback/recording
- ALSA seems to work fine
- Previous versions of pulseaudio used to work (up to ver. 1:0.9.16~test5)
- Additional USB audio devices work (tested it with a VoIP phone and an IK Multimedia StealthPlug)
Thanks in advance

I also tried Kubuntu Karmic A5, but apparently they do not seem to use pulseaudio for audio control, because alc-660vd is eing recognized.

The latest pulseaudio update from the Ubuntu Audio Dev team PPA hasn't solved the issue, but now I have "Dummy Output" instead of "Null Output" under the "Hardware" tab.

I was going to try some settings from #13 above but I don't see that setting... Can you elaborate on "Does your user have permission via PolicyKit or otherwise to access @audio?" My user is an administrator user and all privileges are checked in the User Manager.
The only way I have been able to get sound is by modifying /etc/modprobe.
options snd-hda-intel model=AD198x
The above workaround only works between reboots and apparently uses alsa instead of pulseaudio.
Any ideas? I hope this gets fixed by release time because the Intel graphics are working a lot better in the Karmic version and I'd hate to not be able to recommend the upgrade.
Thanks!

Oh and one more thing... The sound worked on the LiveCD, it's either just after install, or perhaps just after updates after the install that it stopped working.

slmodemd is likely invoked from an initscript or Xsession script. You
can check which package contains it, then list the contents of said
package to see which file to inspect:
dpkg -S bin/slmodemd
Shannon VanWagner (shannon-vanwagner) wrote : Re: [karmic] pulseaudio: card not found - Null Output / Dummy Output | #42 |
So I disabled the Hardware Drivers for the modem. So the slmodemd is not loading now and I have sound everytime.
If you need some sort of output from the slmodemd as installed, I could load it back in. I guess if I ever wanted to use the modem on this machine, I would need to figure out some way to have it coexist with the regular sound.
Also, the big problem I'm having now is that the sound is really quiet, even though I turned up the soft/hard volume switches to the maximum level.
I know this laptop can do much better than that - I've heard it before, when I had use the sudo alsa force-reload before or something. Is there some setting I can change somewhere to have the volume be louder? Like maybe some type of pulseaudio setup wizard. Sorry if I haven't researched pulseaudio as much as I should have already.
I appreciate your attention to the matter.
Regards,
Shannon

It seems that also in my case the issue is with the modem driver - disabling it from Hardware Drivers fixes the sound.

So I figured out how to make the sound louder - it's the PCM volume, which was set to the lowest setting.
The problem is that to change PCM - I had to run alsamixer from the gnome-terminal and change the setting with the keyboard.
I'm thinking it would take anyone who is even noobier than me quite awhile to figure out how to get that working right. In the previous version of Ubuntu, I was able to change the PCM volume from the regular volume controls. So hopefully the sound just works better on the official Karmic release.
If you need for me to respond with any other output, let me know. Thanks again for your help, it's truly appreciated.
Now on to the other problem I've been having.... the partition manager not starting when reinstalling Karmic.
Have a great day!

Shannon, the issue you're experiencing is exacerbated by the fact that some people cannot use the default volume adjustment algorithm due to their hardware being overdriven at PCM settings > 80%.

Strange thing is that alsa detects modem as audio, i think it should be disabled for alsa to think modems are the same sound cards as HDA ATI SB, so pulseaudio get confused between these 2 things. Maybe i am wrong...

As discussed on irc, udev-detect is doing the right thing here. We
cannot assume that just because your hardware is capable of
simultaneously streaming to hw:0,0 and hw:0,6, all configurations must
be.
An example of where this breaks is on older families of Creative Labs
Live and Audigy hardware, where hw:0,0 and hw:0,3 are exclusive.

Well, what if I want to use my modem ? It was working on Jaunty, so this is a regression...and the above fix is just a workaround...
I know this is a proprietary driver, so we can't blame ubuntu dev...Anyway, analog modems are less and less used so it's not a serious regression...
The SmartLink modem daemon is the application part of thedriver for recent modems produced by Smart Link Ltd.
This package replaces (along with hardware access drivers) the olddriver generation (2.7.x) which consisted of kernel modules only.
It needs a kernel driver to access the hardware. This can be eitherrecent ALSA (shipped with a newer kernel (>=2.6.4) with Alsa supportand intel8x0m module) which is sufficient for basic operation anddata/Internet connection, or the SmartLink kernel driver which isprovided by separate packages which you can build using the source fromthe sl-modem-source package.

Downloaded the Karmic RC alternate iso, upgraded distribution from Jaunty, no problem with sound.
Then downloaded the Final Release yesterday upgraded and the sound disappeared.
That was quite alarming.
As others have noted the sound card was not being recognised in Hardware profile. Removing the modem driver restores sound to the system. Sound card is once more recognised by pulseaudio.
Weird problem.

afterwards I get the sound, Everything is working than correctly, only the internal microphone volume have to be adjusted.
Skpe is than also working correctly with the the pulse audio mixer.
Is there a way to have script with the command at start-up after pulse is loaded? It will fix here the issue with detecting Alsa correctly.
It looks to me that Pulse does not detect the Alsa correctly

In oder to get the sound my workarround is currently for your session the steps are:

2.Go than to the Gnome Alsa Mixer (Aplications=

options snd-hda-intel model=3stack-6ch
to the file /etc/modprobe.
The problem is that, like others, i have no devices to configure in sound preferences application (hardware tab). But the sound work.

What isn't immediately obvious to most people is that the modem itself
works fine, and the software driving the modem works fine. In Karmic
*the bug is in PulseAudio*, specifically how module-udev-detect
validates sinks and sources.

I am also affected by this bug. Everything was fine until I activated the restricted driver for my modem. Upon reboot, no sound, and no sound hardware registered in alsamixer or pulseaudio. Issuing 'sudo alsa force-reload' restored sound and placed my sound hardware back in pulseaudio's hardware tab.

Hello,
Updated pulseaudio packages from PPA. Downloaded modem installer from LINUXANT and installed LINUXANT modem ALSA driver and LINUXANT HSF Conexant modem driver.
This time, no errors on the install (progress); but NO SOUND! The installation of the LINUANT packages kills the sound. Under System>Sound, there are no audio devices present.
Had to remove the LINUANT packages (via Synaptic) and rebuild the ALSA modules from source to restore sound.

Indeed, upon inspecting your lsmod output, none of the ALSA drivers
for your sound card are loaded. Have you rebooted?
cement_head (andorjkiss) wrote : | #91 |
yes, the sound works immediately after install - but after reboot, no sound.

I'm not sure what you mean by "install" above. Do you mean a fresh install
of Karmic, the Linuxant modem driver, of alsa-driver (manually), or some
combination?
I'm trying to see which ALSA device is created by the Linuxant driver so
that PulseAudio can be modified as necessary.

So hsfmodem works completely differently (not surprising, I suppose).
If you start it now, does the softmodem work as intended?

If that command doesn't work, you're looking at a driver issue not a pulse one.
jss (jsantossilva) wrote : | #105 |
I'm running Karmic fully updated; updated pulseaudio forcing lucid 0.9.21 by apt-get on terminal.
At first the bug seemed to persist; then I launched GUI system update and some libs seemed
to not have been updated; after updating, devices show up correctly and everything seems to
work, except:
- On every boot, sound is always muted on the output device, set to default
- Volume is at 3%
So, being a newbie to Linux, long time experienced with MS, I ask:
Does this belong here, is this another bug or is any config I should change?
Thanks,

cement_head (andorjkiss) wrote : | #106 |
Well, according to LINUXANT technical support. Their driver works on Karmic Koala. I'm inclined to agree with them as I was JUST using Interpid Ibex and the LINUXANT driver and my modem worked on this same machine. I then did a fresh install of Karmic Koala and now this same modem (same LINUXANT driver) DOES NOT work.
I tried to file a bug with PULSEAUDIO ( Ticket # 746 ) but it was abruptly closed and declared a duplicate - which I thought was silly and rude, because there was no explanation as to why it was deemed a duplicate.
Isn't it somewhat pointless to file bug reports if they get marked as a duplicate and closed if they not resolved?
cement_head (andorjkiss) wrote : | #107 |
Okay.
I installed the LINUXANT packages again and noticed a weird install error:
Building modules for kernel 2.6.31-17-generic, using source directory

-------
I then rebooted and then reinstalled the alsa-linuxant and the HSF modem driver; I had to manually download and install the HSF driver from Linuxant and it all works!!!
So, for some reason, the HSF modem driver barfs on the first install and doesn't find the snd-hda-
In any case, for me, the ubuntu PPA pulse audio updates fixes the modem bug for the HSF modems on an HP6910p running the proprietary LINUXANT modem driver package.

@cement_head, that's one of the same problems I'm having on another machine... per this bug:
https:/
The other problem is that the sound is very fragile... I can easily break the sound into "static crunchiness" by hitting backspace in the terminal 3 times while any sounds (e.g., music) are playing from another application.
I can reset the sound by turning the hardware off and back on from the gnome-volume-
I'd be really happy to be able to: a.) find the place(config file or whatever) where I can change the default sound setting from mute to mid-level on login, and b.) have some batch-script or macro-like way to turn the sound hardware off and then back on, with one-click, or keystroke.
Don't take me wrong, I'm absolutely not complaining about this wonderful and FREE operating system... these are just humble requests... nothing more.

I haven't synced the PPA's package with Lucid's yet, so that symptom
will still appear.

This problem persists in Lucid Lynx with my System76 Pangolin Panp4n laptop. There is some conflict between the package modemmanager and pulseaudio that causes pulseaudio to lose the sound hardware. It replaces it with "dummy" and will not produce sound unless I uninstall modemmanager. As Lucid is supposed to be the bug killer release, this one would be a nice one to dispose of. I'd like to be able to fax things on occasion using my modem, and as it is, the modem is unuseable without sacrificing sound.

Please file a new bug instead of splattering on this one. Be sure to
include the output from sudo fuser -v /dev/dsp* /dev/snd/* /dev/seq*

Barry, please file a new bug as Daniel Chen instructed in the previous comment. This one has already been marked Fix Released. Thanks.
Make sure you have the very latest updates installed, as there was a permissions error that is fixed with the latest updates.
