I just looked at that

ls-l /dev/dsp* /dev/audio* /dev/mixer* /dev/snd/*

IMHO it does not help. or rather it is much more confusing than lsof line I gave. Install lsof.

Some detail, lsof is a command meaning "list open files", which is used in many Unix-like systems to report a list of all open files and the processes that opened them. lsof - Wikipedia, the free encyclopedia

Its a very handy command

lsof installed.

here is the output. So far the sound is working well. cheers.

You can run lsof as a regular user.

Here is an example from my PC with NO sound playing.

oldcpu@hal1000:~> lsof /dev/dsp* /dev/audio* /dev/mixer* /dev/snd/*
COMMAND    PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
pulseaudi 5559  oldcpu   20u   CHR  116,9      0t0 5411 /dev/snd/controlC0

kmix      5591  oldcpu   11u   CHR  116,4      0t0 5351 /dev/snd/controlC1

and then when playing an .mp4 file with smplayer

oldcpu@hal1000:~> lsof /dev/dsp* /dev/audio* /dev/mixer* /dev/snd/*
COMMAND    PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME

mplayer   7783  oldcpu    8u   CHR  116,9      0t0 5411 /dev/snd/controlC0

and then after that finished, here is firefox playing a flash video I uploaded: YouTube - Show: Dancing with the Dragon and the Phoenix

oldcpu@hal1000:~> lsof /dev/dsp* /dev/audio* /dev/mixer* /dev/snd/*
COMMAND    PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME

kmix      5591  oldcpu   11u   CHR  116,4      0t0 5351 /dev/snd/controlC1
npviewer. 7816  oldcpu  mem    CHR  116,6          5390 /dev/snd/pcmC0D0p
npviewer. 7816  oldcpu   12u   CHR  116,2      0t0 4907 /dev/snd/timer
npviewer. 7816  oldcpu   13u   CHR  116,6      0t0 5390 /dev/snd/pcmC0D0p
npviewer. 7816  oldcpu   14u   CHR  116,9      0t0 5411 /dev/snd/controlC0

... so in the example you gave, I see "npviewer" present which suggests to me you have firefox running? or you had it running and it has not let go of the video yet.

[weisuse]

Here is a quick series I did:

It looks like just closing the tab won't turn off the flash, instead I need to quit the firefox to be able to release the device if I want to use it with another program (let's say amarok). Am I right?

last.fm running in firefox (using flash)

~/Desktop> lsof /dev/dsp* /dev/audio* /dev/mixer* /dev/snd/*

kmix 5658 wzhou 12u CHR 116,7 0t0 18746 /dev/snd/controlC0

close the tab

lsof /dev/dsp* /dev/audio* /dev/mixer* /dev/snd/*
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
npviewer. 4773 wzhou 13u CHR 116,4 0t0 18725 /dev/snd/pcmC0D0p

speaker-test hang

quit firefox

kmix 5658 wzhou 12u CHR 116,7 0t0 18746 /dev/snd/controlC0

speaker-test working

restart firefox and youtube (dragon and phoenix)

lsof /dev/dsp* /dev/audio* /dev/mixer* /dev/snd/*

I think so.

It looks like firefox opens the flash app npviewer to play a video, and it remains open until firefox itself is completely closed. Until then, it will not give up the audio device. Note if you check the preferences/settings menu of various multimedia players, you may find a menu item allowing you to select the output module. If you can set that to alsa (advanced linux sound architecture) then do so, as the alsa API will share the audio. I don't know how to do this in firefox.

[weisuse]

now I reboot (didn't quit firefox), after started, all the pages in firefox including youtube automatically loaded and there is NO sound for youtube. BUT if I try amarok, it's fine. So the amarok or related something is occupying the device. Here is the lsof:

lsof /dev/dsp* /dev/audio* /dev/mixer* /dev/snd/*
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
kmix 3891 wzhou 11u CHR 116,7 0t0 4262 /dev/snd/controlC0
pulseaudi 3928 wzhou mem CHR 116,4 4244 /dev/snd/pcmC0D0p
pulseaudi 3928 wzhou 20u CHR 116,7 0t0 4262 /dev/snd/controlC0
pulseaudi 3928 wzhou 25u CHR 116,7 0t0 4262 /dev/snd/controlC0
pulseaudi 3928 wzhou 26u CHR 116,4 0t0 4244 /dev/snd/pcmC0D0p
pulseaudi 3928 wzhou 27u CHR 116,7 0t0 4262 /dev/snd/controlC0

So question will be how to release the device?

It looks to me that pulse audio is the offending package.

Go to Amarok > Settings > Configure Amarok > Engine > Configure Output Engine > Outplug-in ... ensure you have "alsa" selected and not "pulseaudio". That is for amarok-1.4.10. You may have a different Amarok version? From now on leave it set to 'alsa'.

I have amarok-1.4.10. Its current engine is gstreamer/yauap engine. THe other available one is xine engine. I didn't see alsa.

Did not see alsa ? Can you look again ?

From my PC:


Edit - I figure you did not bother to read my post? ... even though I took the time to precisely type the menu to follow:
