Hi,
I'm trying to configure a mythtv box to send sound to my spdif port
AND my analog stereo speakers.
In order to make the spdif port work, I found I needed this in /etc/asound.conf:
#----
pcm.!default {
type plug
slave.pcm "spdif"
}
#----
I thought maybe this would work to send the sound to both....
#----
pcm.!default {
type plug
slave.pcm "front"
slave.pcm "spdif"
}
#----
But that was a little naive... apparently. The sound just goes to
whichever item I put last.
I know right next to nothing about writing alsa config files... and
every example I find is very large, very complicated looking, and
doesn't do what I want.
Can someone tell me how to configure alsa for this?
What I want - exactly - Sound to always go to both the "front" (my 2
channel stereo speakers), and my spdif output, with anywhere between 1
and 5.1 channels... depending on what my source audio has. I also
want mythtv to pass the full 5.1 channels from HD to the spdif port,
while sending the stereo sound to the analog.
Some info:
