Apparently, the firmware doesn't support automatic format detection
completely, and requires this command for the 2ch 32/44.1 kHz modes.
(That 2ch at 96 kHz actually works is even more curious. There already
is that bug regarding listing the seventh format; it's possible that
they completely forgot to report an eighth format.)

Clemens
