I have a PV-BT878P+ w/FM rev. 9D card. I would like to permanently connect an external stereo audio signal to its input, and have that input travel to the tv card's audio output unchanged. I want to do this so I can either listen to an external source, or the TV from the card, or a sound card whose line input is received from the tv card output, without having to change connectors, just invoke a mixer program such as gom or aumixer. Basically I want each sound device to connect in a daisy chain. A careful reading of documentation and source for btaudio reveals that this may not currently be possible. The two mixer devices it creates only appear to adjust the volume for sampled input channels. Is it possible to do this somehow?
