I am pretty sure you are correct but I wanted to make sure that there wasn't some kind of signalling that happened when I switched the active input to the USB. > > But I don't quite follow what you did different between your tests. > Plugging in after boot works fine.

Sorry for the lack of clarity! First time: I plugged the Schiit USB into the laptop before booting the laptop (only one altset for output, two for input for stream0) Second time: I hot-plugged the Schiit USB into the already running laptop (two altsets for stream0, correct behaviour) Third time: I rebooted the laptop after the second time above without unplugging the Schiit (two altsets for stream0, correct behaviour) Fourth time: I halted the laptop, unplugged and replugged the Schiit, booted (only one altset, both output and capture, for stream0). I can try some repeatability testing on these if you like. -- Chris Hermansen · clhermansen "at" gmail "dot" com C'est ma façon de parler. ------------------------------------------------------------------------------ Precog is a next-generation analytics platform capable of advanced analytics on semi-structured data.
