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: http://www.alsa-project.org/db/?f=fe378d28f0dbb5a427b005d20866a762fd37d31a

post output of pactl list or pulseaudio verbose log
you have to change channel mode from 2ch to 6ch to retask the input jacks as output if your motherboard only have three audio jacks at rear panel
do you mean pulseaudio cannot probe the surroun40 or surround51 profile ?
Simple mixer control 'Channel Mode',0 Capabilities: enum Items: '2ch' '4ch' '6ch' Item0: '2ch'
