If I recall correctly, there is a jumper responsible for this on the audio card itself to accomodate that. Mine is like this (3 jacks card). > > Problems are: > -center and lfe have no volume control > -PCM-control controls both front and rear > -Master-control controls only the front speakers Adjustment is unconventional, but straightforward for surround material: 1 - Master at 0. 2 - Adjust rear volume with PCM near maximum required (center-rear balance). 3 - Increase front volume with Master to obtain rear-front balance. 4 - Decrease PCM to lower volume on all speakers. > > with an external amplifier I can live with that. > By the way, the exchange DACs button disappeared - only for me? No, it was removed after alsa 0.9.8. It's now automatically controlled. > > Norbert ------------------------------------------------------- This SF.net email is sponsored by: IBM Linux Tutorials.
