[pulseaudio-discuss] Two mono sinks to a single stereo card with left and right splitted.

I have a quite unusual configuration requirement:

To explain my situation. I have a server which runs mpd. It sends the
music simultaneously to a RTP stream and to my local stereo sound card.
As the server is in a very usefull position in my appartment, the stereo
output is connected to two speakers, one of which is in my kitchen and
the other one is in my bathroom. It enlightens my kitchen and bathroom
with music.

The first problem is this: I want to send the left and right channel of
the mpd program to both speakers. Thus it would have to be downmixed and
sent to both channels of my stereo card. This is because some songs use
panning (and I want to hear both channels). As it is background music, I
don't mind that it is downmixed. However, the RTP stream may not be
downmixed and must remain stereo.

The second problem is this: I want to be able to mute the two speakers
independently. If I'm at the kitchen, I want to be able to mute the
sound in my bathroom. And also if I'm in my bathroom, I want to be able
to mute the sound in the kitchen. Especially because I'm not the only
one who is living in my home, and my taste of music is not that well
received by others.

I hope this is not impossible to do.

Thank you,

Daniël Sonck
