Harlan, alsamixer only works on sound cards that have mixers. Not all sound cards have mixers, and even if they they do the mixer might not be enabled in the Alsa driver. For instance, my $500 RME HDSP 9652 has a mixer, but alsamixer doesn't control it. There's another app that does that for me. How's that for confusing! ;-) Take a look at the amixer command for setting your output levels manually. Specifically the 'amixer cset numid=5' portion of amixer. You can also script them later when you figure out what you want for levels. Ses man amixer for some examples. Mark -- [EMAIL PROTECTED] mailing list
