You did not provide any information about kernel or OS. Are you not using pulse audio? On the alsa page there are some instruction how to configure the devices properly, so that you have consistent mapping. Example username@hostname# pico /etc/modules.conf # OSS/Free portion - card #1 alias sound-slot-0 snd-card-0 alias sound-service-0-0 snd-mixer-oss alias sound-service-0-1 snd-seq-oss alias sound-service-0-3 snd-pcm-oss alias sound-service-0-8 snd-seq-oss alias sound-service-0-12 snd-pcm-oss # OSS/Free portion - card #2 (cmipci) alias sound-slot-1 snd-card-1 alias sound-service-1-0 snd-mixer-oss alias sound-service-1-3 snd-pcm-oss alias sound-service-1-12 snd-pcm-oss Again, if your card is not supported by ALSA ... even if you see it somehow correct in alsamixer, does not mean it would work without issues. Output of following commands could be of interest though and ask ALSA if your card is fully supported and how it can be configured based on the chip you have uname -a lsmod | grep snd amixer amixer -c 0 amixer -c 1 It could be something in kmix, but I doubt it. regards --------------------------------------------------------------------- To unsubscribe, e-mail: trinity-users-unsubscribe@xxxxxxxxxxxxxxxxxxxxxxxxxx For additional commands, e-mail: trinity-users-help@xxxxxxxxxxxxxxxxxxxxxxxxxx Read list messages on the web archive: http://trinity-users.pearsoncomputing.net/ Please remember not to top-post: http://trinity.pearsoncomputing.net/mailing_lists/#top-posting
