Sound (optical) gone after upgrade [SOLVED]

bmentink · 2012-06-08 07:50:18

Hi All,

I have had great fun after the last upgrade. First problem nvidia driver would not load, solved by allocating more ram on the kernel line (in /boot/menu.1st
Second problem is I no longer have a visible optical sound interface (the one on the motherboard, intel chip ) The nvidia hdmi sound channel is there though ..
pavucontrol shows no optical device just nvidia hdmi ..

Anyone know how to debug this?

You mention pavucontrol , so i guess you're using pulseaudio ?

The following is for alsa, but it will help to determine if your audio devices are detected correctly.

from console run :

aplay -l

and post the output.

It should look similar to this :

**** List of PLAYBACK Hardware Devices ****
card 0: NVidia [HDA NVidia], device 0: ALC883 Analog [ALC883 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: NVidia [HDA NVidia], device 1: ALC883 Digital [ALC883 Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: HDMI [HDA ATI HDMI], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Hi, thanks for the reply. Yes, I am using pulseaudio, it seems to be the Arch default now.
Here is the dump of devices:

**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC1200 Analog [ALC1200 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 3: ALC1200 Digital [ALC1200 Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: NVidia [HDA NVidia], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: NVidia [HDA NVidia], device 7: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: NVidia [HDA NVidia], device 8: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: NVidia [HDA NVidia], device 9: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Looks like card0, device 3 is what I want ... but why is it not showing up in pavucontrol now?

pulseaudio is required for Gnome and a few other porgrams, but KDE, XFCE , openbox and afaik all other WM/DE can work with either pulse or alsa.

What WM/DE are you using ?

Also look for a .asoundrc file in your home folder (not sure if it's in a subdir or not) and post it.

There is no .asoundrc file and I am using Gnome3 which uses pulse I believe ..
I used analog sound briefly last night so I could watch TV (it is my media box) but on a reboot this morning, even analog has stopped working ..

Help please, TV without sound sucks big time ..

I'm experiencing the same problem. Yesterday vlc didn't have sound, today after I tried to troubleshoot it I lost the sound to everything. I use KDE with VLC as my phonon backend and S/PDIF as my connection. I did notice that there are much less options in system settings. Before the upgrade I could set my audio to S/PDIF now I can only chose from HDMI and digital.
EDIT: Well this is awkward. My sound actually works, I just didn't have the speakers turned on. But VLC still doesn't work. So there's that.

ok, looks like we need to check the basics first.

from console run alsamixer, select the card with the s/pdif output and verify is is not muted (it should show OO at the bottom for that channel).

Note the name of the S/pdif channel, run aplay --list-pcms to make sure you have the correct pcm name for it.
then try aplay --device=pcm_name /path/to/any/soundfile
(/usr/share/sounds has many) .

If that commands outputs sound, you'll know for sure the s/pdif output is working.

This is what aplay --list-pcms returns:

As you see I only have analog and hdmi devices, no spdif ..

this should be the optical output of the intel chip, it seems it is detected as a hdmi output, not s/pdif.

hdmi:CARD=Intel,DEV=0
    HDA Intel, ALC1200 Digital
    HDMI Audio Output

bmentink · 2012-06-12 06:45:44

Thanks for that. I set XBMC to use the "HDMI Intel device 0" and selected the usual "Optical" output and that worked ...
I have no idea why it is naming it hdmi ... that makes no sense at all .. oh well works now .. thanks again.

Marking solved.
