the following patch was just integrated into master: commit 1e1a1798faf9715ceb2bd34b619c3c21f03ce89a Author: Rudolf Marek r.marek@assembler.cz Date: Tue Apr 2 20:51:15 2013 +0200
ASUS F2A85-M: Provide HD Audio verb table for Realtek ALC887-VD
Use the same HD Audio [1] verb table for the Realtek ALC887-VD audio chip as the one set up by the proprietary vendor BIOS. Linux’ ALSA exposes this pin configuration under the virtual filesystem sysfs.
/sys/class/sound/hwC1D0/init_pin_configs
The script `alsa-info.sh` [2][3] is able to decode the table.
Only one channel audio playback (rear connectors) is tested [4], which worked already before.
