Sound working as root, but not as a regular user...

I'm trying to get Debian 5 with LXDE up and running.

Sound is working for root after installing alsa packages, and configuring with:

Code:

alsaconf
alsactl store
speaker-test

speaker-test produces sound from the speakers when logged in as root from a terminal window.

No sound is, however, produced as a regular user. Running speaker-test as a regular user produces the following output at a terminal window:

Code:

ALSA lib confmisc.c:768:(parse_card) cannot find card '0'
ALSA lib conf.c:3513:(_snd_config_evaluate) function snd_func_card_driver returned error: No such file or directory
ALSA lib confmisc.c:392:(snd_func_concat) error evaluating strings
ALSA lib conf.c:3513:(_snd_config_evaluate) function snd_func_concat returned error: No such file or directory
ALSA lib confmisc.c:1251:(snd_func_refer) error evaluating name
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 pcm.c:2144:(snd_pcm_open_noupdate) Unknown PCM default

It doesn't seem as though the regular user is able to see the sound driver. The alsaconf script checks for root privileges and won't run otherwise. Any ideas?

Thanks a bunch.

If you run

Code:

id

as a regular user, you can see the group memberships of the user? It may be beneficial to run the alsa daemon as an unprivileged user, maybe called alsa-daemon, and add the regular users to it's group?

Sounds like you need to make the regular user(s) part of the audio group.
