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 conf.c:3513:(_snd_config_evaluate) function snd_func_card_driver returned error: Aucun fichier ou répertoire de ce type 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: Aucun fichier ou répertoire de ce type 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: Aucun fichier ou répertoire de ce type ALSA lib conf.c:3985:(snd_config_expand) Evaluate error: Aucun fichier ou répertoire de ce type 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,
