Hi!
One possibility might be to create a plugin for it. I don't exactly know
about the channels of a 5.1-system. But if they are there as pcm-devices, then
you could try mapping the channels 0 and 1 to the other channels. It could
look like:
pcm.mystereo
{
type plug
ttable.0.0 2
I got my 5.1 soundsystem working. If the sound is 5.1 all sound channels
work.
Now I want stereo not only to be on the front channel.
In alsamixer I turned the option Duplicate Front on, now I have the
stereo sound on fropnt and rear channels but not on Center / LFE channels.
How to turn sound on
