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:

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'

How would one do that ? Pulseaudio only offers Stereo profiles.

Yes, but I can't use it with aplay even without pulseaudio running.

amixer -c0 set "Channel Mode" "6ch"
you can logout and login after you set the channel mode to 6ch so that
pulseaudio is restarted.
this also require
alsactl store this setting before computer shutdown
alsactl restore this setting after computer boot

try speaker-test -c 6 -t wav -Dhw:0,0 after you set the channel mode to 6ch

do it really work since rear mic become active port even when it had been
retasked as output ?
Ports:
analog-input-front-mic: Front Microphone (priority: 8500, not available)
analog-input-rear-mic: Rear Microphone (priority: 8200, available)
analog-input-linein: Line In (priority: 8100, available)
Active Port: analog-input-rear-mic

The 6 outputs work at the same time. I didn't try it as a mic as I don't
have a mic here...
