No sound at all on openSUSE 12.2

[oldcpu]

@seveninstl

oldcpu, I’m having the same problem as samimk. I’ve followed the instructions in this post, but still have no solution(s). I’m very curious about your suggestion to check to see if an application is using and seizing the sound device. Can you please explain how I can do this, or post a link to instructions on how to do this? Thank you very much!

( I would like to know how to do this to investigate my problem, but I also think it would just be cool to see what resources apps are using! :))

Note please my blog entry on using pulse audio with pulse audio volume control (pavucontrol) : https://forums.opensuse.org/blogs/oldcpu/pulseaudio-basics-opensuse-pavucontrol-96/

wrt your question , to see if another application has seized the audio device and is refusing to share it, you need to list the files opened by the appropriate process.

Try looking at the open files associated with /dev/snd … ie …:

lsof /dev/snd/*

Try running that when sound is working ok. Also when it is not working ok. look for differences.

For with pulse audio, and functioning sound (but no media application running), what I get is:

oldcpu@corei7-920:~> lsof /dev/snd/*
COMMAND    PID   USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
pulseaudi 5072 oldcpu   22u   CHR  116,9      0t0 9758 /dev/snd/controlC0
pulseaudi 5072 oldcpu   27u   CHR  116,9      0t0 9758 /dev/snd/controlC0
pulseaudi 5072 oldcpu   33u   CHR  116,3      0t0 9751 /dev/snd/controlC1

and then with smplayer playing (which is configured to use pulse audio on my pc)

oldcpu@corei7-920:~> lsof /dev/snd/*
COMMAND    PID   USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
pulseaudi 5072 oldcpu  mem    CHR  116,6          9755 /dev/snd/pcmC0D0p
pulseaudi 5072 oldcpu   22u   CHR  116,9      0t0 9758 /dev/snd/controlC0
pulseaudi 5072 oldcpu   27u   CHR  116,9      0t0 9758 /dev/snd/controlC0
pulseaudi 5072 oldcpu   33u   CHR  116,3      0t0 9751 /dev/snd/controlC1
pulseaudi 5072 oldcpu   34u   CHR  116,9      0t0 9758 /dev/snd/controlC0
pulseaudi 5072 oldcpu   46u   CHR  116,6      0t0 9755 /dev/snd/pcmC0D0p

and by looking at ‘pavucontrol’ tabs one can see how smplayer is configured to use pulse.
