Hi,
I just transformed an old Pentium III 500 into a headless jukebox. It's
installed in the basement, near the stereo. There's only a base CentOS
system on it (GNOME unchecked, package customization checked and then
everything unchecked). From there on, I just installed the ALSA utils,
and vorbis-tools. The machine is only supposed to do one thing (and to
do it well, UNIX philosophy :oD): fetch an audio stream (produced by
MPD/Icecast upstairs on a big PC) and then output it from the soundcard
to the AUX IN from the stereo.
I have a partial - and near-total - success, in that everything runs
fine... as root user. Whenever I try to run alsamixer as a normal user
on that box, I get the following error message:
[kikinovak@jukebox ~]$ alsamixer
alsamixer: function snd_ctl_open failed for default: No such file or
directory
Something similar happens with ogg123, which runs fine as root, but
produces the following error message as plain user:
[kikinovak@jukebox ~]$ ogg123 http://babasse:8000/jukebox.ogg
ALSA lib confmisc.c:768:(parse_card) cannot find card '0'

ALSA lib pcm.c:2184:(snd_pcm_open_noupdate) Unknown PCM default
=== Impossible de charger le pilote par défaut, et aucun autre pilote
n'est indiqué dans le fichier de configuration. Terminaison.
Now I guess there must be something missing, because on my other
machines (with a full-blown desktop installed), alsamixer runs fine as
normal user.
Any idea what could be wrong here?
Cheers from the hot south of France,
Niki
