control 6 audio channels seperately
I have a 5.1 soundcard, and use ALSA as sound system. I'm not really satisfied with the ALSA mixer, cause the only two volumes that I can control are front/rear-left and front/rear-right. center and subwoofer are always 100%. I'd like to be able to control every single channel.. is there any way to do that? maybe an ALSA plugin or something?
