Hello list,
I was with my sound (alsa) work perfectly on my laptop, but for an
unremembered reason I ran alsoconf as root. It causes the strange
behavior of alsplayer, aplay, etc., to stop working for normal users.
They only run for root. I checked groups and permissions, and it seems
ok. All users are in group audio, as well as related devices and proc
files. I do not want to install all the system again, so I wonder if
anyone has any idea of what is happening... If I run aplay, for example,
I get the following error message:
~ $ aplay wavs/scieh.wav
ALSA lib confmisc.c:769:(parse_card) cannot find card ''
ALSA lib conf.c:3510:(_snd_config_evaluate) function
snd_func_card_driver returned error: No such device
ALSA lib confmisc.c:392:(snd_func_concat) error evaluating strings
ALSA lib conf.c:3510:(_snd_config_evaluate) function snd_func_concat
returned error: No such device
ALSA lib confmisc.c:1251:(snd_func_refer) error evaluating name
ALSA lib conf.c:3510:(_snd_config_evaluate) function snd_func_refer
returned error: No such device

ALSA lib pcm.c:2144:(snd_pcm_open_noupdate) Unknown PCM default
aplay: main:545: audio open error: No such device
The wierd thing is that as root, I get no error and the sound is played
perfectly.
Also, sound in skype was ok, but now, it does not work too.
My lspci | grep -i audio:

Any idea?
did you register yourself as audio_user in /etc/group?
