[alsa-devel] Surround sound not working on ALC887 based motherboard

[Olivier Crête]

Hello,

I have a Asus P5G41T-M LX Plus motherboard which is ICH7 + Realtek
ALC887-VD, alsa only lets me access the first 2 channels (stereo), but
not the 6 other ones. It works fine in Windows.

Trying to run this after killing pulseaudio fails:

$ aplay -D surround40:0 -f S16_LE -r 44100 -c 4 /dev/zero -v
Playing raw data '/dev/zero' : Signed 16 bit Little Endian, Rate 44100 Hz, Channels 4
aplay: set_params:1239: Channels count non available


Output from alsa-info:
