 Posted: Wed Feb 10, 2010 1:02 am Post subject: ALSA: Device or resource busy [SOLVED] |
 |
|
Hi everyone,
I had this problem for some time now and cannot find any solution. Somehow my dmix is broken, if I understood alsa correcty. I just can get one application using alsa, whatever second application I start I get something similar to:
| Code: |
[AO_ALSA] Playback open error: Device or resource busy
|
I can't find any bigger difference to the configuration of my other installations, but there it works.
My emerge --info:

Can you please provide a little more information regarding which applications you are trying to use? Also, are you running KDE?

| Yes, right , this was not too clear from my post. I don't use KDE or Gnome and it happens with any application. If one is running using ALSA, I can't make another one use ALSA. For example, if listen to mpd, starting mplayer to play a movie or sound file, I get the "resource is busy" warning. Same with skype, flash in firefox, vlc... Basically everything installed which could make any sound. |

Are you using pulseaudio?
Does /etc/asound.conf exist?
Or does ~/.asound.conf exist? |

By the way, thanks for the replys. I'm not using pulseaudio, I have /etc/asound.conf:
| Code: |
~ $ cat /etc/asound.conf
pcm.!default {
type hw
card Intel
}
ctl.!default {
type hw
card Intel
}
|
I had to add this because some programms started to play music to the webcam microphone. |

lol, try disconnecting the webcam if possible and moving /etc/asound.conf out of the way. This way, we can see if the asound.conf needs some more editing. |

Well, you get two things :
1/ If this is your asound.conf and get no $HOME/.asoundrc, then your dmix is not broken... 
You... simply... do not use it ! 
2/ With such an asound.conf, it is likely that things such as flashplayer will capture the default audio device and make other sound apps see that device busy. => for example, no sound from other audio apps when you get a flashplayered browser running in the same time !
About this last question, you can follow this thread : http://forums.gentoo.org/viewtopic-t-814115-highlight-.html |

This worked, now I just need to figure out how to tell the programs the right audio device. With webcam plugged in at boot, this is taken as default alsa device.

| Well, at the moment, it seems to work. I didn't modify alsa.conf or anything, just removed /etc/asound.conf, but after some reboots, the USB devices never gets the default device and everything seems to work correctly. So, thanks for the help everyone. |

Hi,
I have exactly the same problem. Unfortunately, the link http://alsa.opensrc.org/index.php/MultipleCards#Understanding_.2Fetc.2Fmodprobe.d.2Falsa.conf is not working.
How can I prevent my webcam from being a default device? |
