fixing sound in debian

September 22nd, 2008  |  Published in Recipes

I’m running debian lenny/sid with  kernel 2.6.26-1 on my workstation and for a while, my audio hasn’t been working in most applications (I was most annoyed by the lack of sound in flash), though it has been working in amarok.  I was getting error messages like this when trying to do audio playback.  These particular messages are from Ekiga:

ALSA lib confmisc.c:1286:(snd_func_refer) Unable to find definition 'defaults.namehint.extended'
ALSA lib conf.c:3513:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory
ALSA lib conf.c:3985:(snd_config_expand) Evaluate error: No such file or directory

ALSA lib conf.c:3985:(snd_config_expand) Evaluate error: No such file or directory
ALSA lib pcm.c:2144:(snd_pcm_open_noupdate) Unknown PCM plughw:0

I finally looked into this and was able to fix it with the simple command

 $ sudo asoundconf reset-default-card
