I experienced similar troubles just a while back with my Realtek ALC662 chip. I'm not claiming to understand why, but it turned out I needed to add the following to my /etc/modprobe.d/alsa-base.conf: options snd-hda-intel model=3stack-6ch-dig After reboot, a control pops up in alsamixer, enabling me to switch between 2 and 6 channels. Good luck! /Eric On 2010-08-23 22:50, Андрей wrote: > Hi, everybody :) > > //This is my 1st talking in mailing lists, so please sorry me if I'll be do > something wrong. > > Please, help me with problem in support by ALSA my soundcard.
