Hi, I am running Slackware 12.0 on the system mentioned above with alsa-driver-1.0.15rc2 alsa-lib-1.0.15rc2 alsa-oss-1.0.14 and alsa-utils-1.0.15rc1. My kernel is 2.6.21.5. My /etc/modprobe.d/sound looks like: alias snd-card-0 snd-hda-intel alias sound-slot-0 snd-hda-intel options snd-hda-intel position_fix=1 model=3stack With this I get 5.1 sound but if I set model=3stack-dig (and IEC 958 appears in the mixer) it is impossible to get 5.1 sound, patch_realtek.c though suggests you should use the latter one or it even should auto detect (I am not a programmer). Has anyone a suggestion on how to accomplish this? Other thing I note, this mobo hass 3 jacks at the back and 2 at the front. Is this still a 3stack? Some more info (model=3stack)is below, Kind regards, Maarten #lspci -vv 00:10.1 Audio device: nVidia Corporation MCP51 High Definition Audio (rev a2) Subsystem: ASUSTeK Computer Inc.
