btaudio provides /dev/dsp, a soundcard interface for (in this case)
reading/recording uncompressed audio, matching the /dev/video to
read/record the uncompressed video.
The PVR card compresses itself and of course includes audio in the MPEG
stream, so it reads the audio internally and MythTV reads it together
with the video stream in a single MPEG stream.
No need for btaudio or the like.
