Hello, for quite some time the "Smart 5.1" function in alsa is not working
properly when motherboard has only 3 audio jacks.
Me and Raymond on alsa-bugtracker have been trying to solve the issue for
a long time but were unsuccessful.
Please take a look at this alsa bug ticket:
It contains A LOT of info on the problem + steps that we tried, which
included patching the code.
Synthom : NO "Surround" , "Center" and "LFE" Control and switch with
VT1708S on a motherboard with 3 audio jacks
Also NO surround sound.
speaker-test -c 4 -t wav -Dsurround40
Channels count (4) not available for playbacks: Invalid argument
Setting of hwparams failed: Invalid argument
Please advise if you can.
