At present, the sound interface gives access to anyone in audio group, of which user (brownh) is a member. I apparently have a permission problem, but it does not seem to involve /dev/dsp0: Here is the setup:
$ ls -l /dev/dsp0 crw-rw---- 1 root audio 14, 3 Aug 20 19:53 /dev/dsp0 # cat /etc/group | grep audio audio:x:29:brownh This command issued by root does play a test file: # aplay /opt/tmp/test.wav Playing WAVE 'test.wav' : Unsigned 8 bit, Rate 22222 Hz, Mono However, if user tries it: $ aplay /opt/tmp/test.wav ALSA lib confmisc.c:550:(snd_determine_driver) could not open control for card 0 ALSA lib conf.c:3461:(_snd_config_evaluate) function snd_func_card_driver returned error: Permission denied ALSA lib confmisc.c:387:(snd_func_concat) error evaluating strings ALSA lib conf.c:3461:(_snd_config_evaluate) function snd_func_concat returned error: Permission denied ALSA lib confmisc.c:945:(snd_func_refer) error evaluating name ALSA lib conf.c:3461:(_snd_config_evaluate) function snd_func_refer returned error: Permission denied ALSA lib conf.c:3930:(snd_config_expand) Evaluate error: Permission denied ALSA lib pcm.c:2068:(snd_pcm_open_noupdate) Unknown PCM default aplay: main:508: audio open error: Permission denied Apparently, /usr/share/alsa/alsa.conf is having trouble finding /dev/dsp0, but I really don't understand the errors above. When I use xmms, I get the same errors with some additional information: $ xmms /opt/tmp/test.wav Message: device: default ** WARNING **: alsa_get_mixer(): Attaching to mixer hw:0 failed: Permission denied ALSA lib confmisc.c:550:(snd_determine_driver) could not open control for card 0 ... ALSA lib pcm.c:2068:(snd_pcm_open_noupdate) Unknown PCM default ** WARNING **: alsa_setup(): Failed to open pcm device (default): Permission denied and a window pops up: Please check that: Your soundcard is configured properly You have the correct output plugin selected No other program is blocking the soundcard When I pipe the sound file directly to the interface: $ cat /opt/tmp/test.wav >/dev/dsp0 bash: /dev/dsp0: Permission denied It plays if done by root, but very slowly. I'm running kernel 2.6.8-2-686 with sarge. I'm using an Audigy Gamer card, and the onboard sound sc97 chip is disabled in BIOS. -- Haines Brown KB1GRM -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
