Vchans is able to control volume in software when there lack of hardware
support, but it breaks AC3 stream pass-though. So choosing between them
I have blocked software volume control in driver manually for digital
connectors. To get it back you may in hdac.c change line
if (pdevinfo->play >= 0 && !pdevinfo->digital) {
to
if (pdevinfo->play >= 0) {
May be last changes in 8-CURRENT will allow them coexist, but not for 7.2.
