Could not open audio device for playback
udiotestsrc wave=sine freq=512 ! audioconvert ! audioresample ! gconfaudiosink profile=music: Could not open audio device for playback. Device is being used by another application.
Heron. Sound worked just fine yesterday. Seen this as a bug-report on the internet after googling, but can not find any fix to it. All help will be apriciated: )

Try restarting the computer and see if the problem solved. Indeed maybe "Device is being used by another application." so if you restart, "another application" may leave the sound device free.
Also try closing all other applications that may use sound (sometimes even firefox cam make this problem (flash player uses the sound device))

Rather than fulling rebooting, you could also log out, hit Ctrl-Alt-F1 and login to a terminal. Then type:
Hit Ctrl-Alt-F7 and log back in.Code:pkill -9 -u your_username exit
Don't try to make something "fast" until you are able to quantify "slow".

I am having the same problem. NO sound on video's or youtube. Following these instructions made me lose video sound.

What you have to do is to find which application may be grabbing the sound from you.
This command should list you all the processes the machine is running. Probably that application was launched by your username so you only need to find it and kill it with:Code:ps -ef
My mplayer was blocking my sound so I just killed all instances related to it and my sound was released.Code:kill -9 id_of_the_process
Hope this helps.

1. You cannot kill zombie processes with the kill command. That is why they are called "zombie"
2. You should only get zombie processes if the parent process is behaving badly or if you have killed init. To kill zombie processes, you may want to kill their parent processes and let init kill them.
3. Zombie processes should not take up the audio buffer, but I am not sure about that...

I've got the same problem. And there is nothing in list of devices, so i can't even choose one.
my /etc/modprobe.d/sound contains:
alias snd-card-0 snd-emu10k1
options snd-emu10k1 index=0
alias snd-card-0 snd-hda-intel
options snd-hda-intel index=1
That's seems to be ok, but it does not work from yesterday. I've even compiled a new reknel, because of another problem, and it does not work in both of them.

Correct me when I am wrong, but this sounds like the famous PulseAudio bug.
In that it can only use one source at the time.
I use ALSA instead of PulseAudio because of this. However it seems this bug has been fixed in Intrepid.

I'm using Intrepid and I just got the same error message. Is there a way to disable pulseaudio?

I don't think the bug was resolved, for I also got the same error message in Intrepid.
I don't know how to disable pulse audio, but I can confirm that killing the pulseaudio process made the error go away and I got my sound back. Mine was related to flash, I'm sure. Not sure how safe killing the pulseadio process is, though.
