So, i've already configured it for playing real 5.1 sound with real 5.1 sound files, but i've got no duplication of sound with stereo files - but i want it (they've sounded better with my rear & sub-speakers, even through they are not 5.1). Could i somehow set it, not globally, but only for some applications? What man page i should refer to? 2010/1/24, Alexander Motin <mav@freebsd.org>: > Hi. > > Mikle Krutov wrote: >> I've got MSI mb 760GTM-P33 with ATI hd audio chip (pciconf shows ' >> device = 'IXP SB600 High Definition Audio Controller''). >> 5.1 sound worked on 8.0-RELEASE (sound was on every channel, but i >> could not change vol per-channel, only globally), and after updating >> to -STABLE - i've got only 2 channels working. >> Any ideas about that? > > Previously you had 2 channels of stereo playback duplicated to every > channel pair of your 5.1 system.
