Sounds OK. I assume that you were routing the outputs for each track
directly to the hdsp pcm playback ports?

This is strange. Are you using any other jack clients and/or inserts

I assume you disconnected the track outputs from the hdsp playback ports?
I don't know why you would need to take the bus level down here, jack
should be doing the same mixing on the bus ports as it did on the alsa

I admit that I don't know that would cause this either. My testing
gave normal results (although i'm not running at 192). It almost
sounds like some outputs were being exported twice to the same channel
