[MS-7623, VIA VT1828S, Green Headphone Out, Front] No sound at all

[Fabrizio Gennari]

The same PC can boot WIndows: the headphones work correctly there (even to the point that the default audio output is automatically muted when the headphones are plugged in).

The headphones have an integrated microphone, which is also plugged in the (pink) front connector. The microphone works OK.

There is an HDMI connector as well as the front and back jack connectors. Without adding radeon.audio=1 to the kernel boot options, the HDMI output on the same PC booted with Ubuntu does not work.

you have to turn off independent headphone if you are using pulseaudio
since pulseaudio does not allow multi streaming

in windows you can play stereo to the front panel headphone while playing 5.1 to rear panel jack

in linux you can use hw:0,2 VT1828S HP [VT1828S HP]

Simple mixer control 'Independent HP',0
  Capabilities: enum
  Items: 'OFF' 'ON'
  Item0: 'ON'

the rear panel jacks should not be muted after the headphone is plugged when independent hp is ON

since the driver should automatically disable auto mute in order to support multi streaming

Sorry, I don't understand what I am supposed to do in point #2. How can I "use hw:0,2 VT1828S HP [VT1828S HP]"?

[Raymond (superquad-vortex2)]

use those application which allow you to specify playback and capture device

mplayer -ao alsa:device=hw=0.2 foo.wav

as windows allow this, why linux cannot have this feature in pulseaudio ?

http://www.intel.com/support/motherboards/desktop/sb/cs-020642.htm#multistream

[Fabrizio Gennari (fabrizio-ge)]

No way to fix the whole system (rather than being forced to use one application, which isn't even installed)?

However, if it can help testing, I know how to make pipelines with gst-launch-0.10. Which para,eters should be passed to alsasink to do the same?

[Raymond (superquad-vortex2)]

in theory you can create a front panel headphone path which use hw:0,2

but pulseaudio does not support playing audio streams to different soundcard even when you have two sound cards

http://www.freedesktop.org/wiki/Software/PulseAudio/Backends/ALSA/Profiles

[Fabrizio Gennari (fabrizio-ge)]

If I type

gst-launch-0.10 uridecodebin uri=file://<path of sound file> ! alsasink device=hw:1,3

I can hear the sound through the monitor's speakers, and with

gst-launch-0.10 uridecodebin uri=file://<path of sound file> ! alsasink device=hw:0,2

I can hear the sound through the headphones.

Yet, If I use gnome-control-center -> Audio (which, if I understood correctly, simply instructs pulseaudio which device to use), when choosing Analog headphones, no sound comes at all, while when choosing HDMI/DisplayPort sound comes from the monitor speakers.

So: the headphones work, but there's something wrong in pulseaudio. But what?

[Fabrizio Gennari (fabrizio-ge)]

Also, I don't understand what multiple streaming has to do with this, since I don't want to hear sound on two devices at the same time: speakers only when headphone unplugged, and headphones only when headphones plugged.

Status changed to 'Confirmed' because the bug affects multiple users.

[Raymond (superquad-vortex2)]

you have to switch off indeondent headphone if you ewant auto mute of the speaker when headphone is plugged

try latest alsa driver

https://wiki.ubuntu.com/Audio/UpgradingAlsa/DKMS

[Fabrizio Gennari (fabrizio-ge)]

There must have been some problems in communicating the problem, seeing as it's been misunderstood constantly.

Auto mute of the speaker is a nice-to-have feature, but _it is not the problem_.
There's nothing wrong with ALSA: the fact that gst-launch with alsasink works should already have pointed out to that. However, I tested an even more direct way to prove that

aplay -D hw:CARD=HDMI,DEV=3 <a WAV file>

sound correctly played from the monitor's speakers

aplay -D hw:CARD=SB,DEV=2 <a WAV file>

sound correctly played from the front green headphone jack (as long as a headphone is connected there)

aplay -D hw:CARD=SB,DEV=0 <a WAV file>

sound correctly played from the rear green headphone jack (as long as a headphone is connected there)

aplay <a WAV file>

sound correctly played from the selected PulseAudio device (using gnome-control-center sound's window to select a device), AS LONG AS THE DEVICE IS NOT ANALOG HEADPHONES. If the selected device is analog headphones, no sound is played at all (needless to say, this happens with headphones plugged)

This is still happening with the recent 13.04

card 0: SB [HDA ATI SB], device 2: VT1828S HP [VT1828S HP]

when independent headphone is ON

aplay -D hw:0,2 Foo.wav

[Fabrizio Gennari (fabrizio-ge)]

OK, tried
aplay -D hw:0,2 Foo.wav
: it works. When running that, sound can be heard from the headphones when they are plugged to the green front connector

[Fabrizio Gennari (fabrizio-ge)]

I tried the Ubuntu 13.04 live cd: with that it works! Sound from the headphones using pulseaudio. Headphones have to be manually selected, but who cares.

So, what can be wrong with Ubuntu installed on the HD? Some wrong configuration bit?

[Fabrizio Gennari (fabrizio-ge)]

Solved. Well, haven't found the cause, but, after uninstalling libasound2 (which caused uninstall of most of the system, including ubuntu-desktop and pulseaudio) and reinstalling it, now the headphones work again under pulseaudio
