SVN commit 850151 by mkretz:

backport: I didn't realize HalAudioInterface needed the fix for handling the
incompatibility in HAL, too. Now, in order to find out what type of soundcard it
is, don't look at the direct parent device object but the parent of the parent
instead (for newer HAL only). Finally my USB device is detected as such again.
