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. -- Alexander Motin
