The "plug" plugin should automatically downmix multichannel data before
sending it to the dshare plugin.

What is the output of "aplay -v -D channel:0 somestereo.wav"?

>         slave.pcm  "channel:" +$CHANNEL  # can't figure out how to concat

That line would have to be written like this:

        slave.pcm { @func concat strings [ "channel:" $CHANNEL ] }


Regards,
Clemens



thanks for the syntax.

The output from the aplay statement is nothing.  I get no sound output at all
when I play a mono wav file it works great.

No big deal though, I put in the route statements and now it works like i want it too.
with both stereo, and mono files.

thanks for your help.
