Hi, 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, Dani?l Sonck
