Hi, I've problems configuring the following use-case with Pulseaudio: - 1x system-message mono sink - 1x music stereo sink - 1x video multi-channel (mono - 7.1) sink with up-/down-mix - 1x internal stereo sound-card (priority 0) - 1x stereo USB-speakers (priority 1) - 1x 5.0 USB audio-interface (priority 2) - there should be one master volume-control (sink?) for all three sinks (system message, music, video) - sound-card sink specific volume-control should be usable to equal the absolute volume of the three sound-cards - external sound-cards should be pluggable/removable without interruption of audio - the current playback sound-card should be switched by highest priority when plugged in/removed - when the USB audio-interface is plugged in stereo left/right (S/PDIF input channel 5/6) should be routed to the video sink - system-message mono should be routed to front-center for the USB audio-interface and stereo for the stereo sound-cards - music sink should always be stereo on all devices How can i achieve this? Thanx for any hint, Renne
