auhal: Fix SPDIF support

The recent changes to auhal had it using an AudioStreamBasicDescription
array when looking at the stream properties. However, the proper type is
AudioStreamRangedDescription. This patch corrects that, and then accesses
the AudioStreamBasicDescription inside it as necessary.
