Had a response over on alsa-devel mailing list, but the suggestion did not
work. Newer kernels support the QUIRK_AUTO_DETECT parameter which once
again worked for 8 channels of capture, but failed for playback.

I am pretty much out of ideas at this point. Here is the output of an
attempt to just use the R16 for stereo playback. There are some maxpacket
errors on the MIDI interface (though it works fine) and errors in getting
the sample rate from the playback and capture addresses for the R16, as well
as errors in setting the sample rate for the playback address (0x03). If
anyone has suggestions on what to do with this info (I also posted on
alsa-devel), please let me know.
