I'm using mpg321 to play MP3 files, and I get a bunch of output if I run it as a non-privileged user: ALSA lib confmisc.c:560:(snd_determine_driver) could not open control for card 0 ALSA lib conf.c:3479:(_snd_config_evaluate) function snd_func_card_driver returned error: Permission denied ALSA lib confmisc.c:392:(snd_func_concat) error evaluating strings ALSA lib conf.c:3479:(_snd_config_evaluate) function snd_func_concat returned error: Permission denied ALSA lib confmisc.c:955:(snd_func_refer) error evaluating name ALSA lib conf.c:3479:(_snd_config_evaluate) function snd_func_refer returned error: Permission denied ALSA lib conf.c:3948:(snd_config_expand) Evaluate error: Permission denied ALSA lib pcm.c:2090:(snd_pcm_open_noupdate) Unknown PCM default ALSA snd_pcm_open error: Permission denied On which files/devices do I need to fix the permissions so that these warnings don't occur? I would also like to be able to run alsamixer as a non-privileged user. Thanks, Patrick
