> maximum amount of different streams played back at once.

Well streams can be inactive as well, so this was not entirely accurate... See
Section 2.2 of HDA spec for what a stream is in this context.

What I'm after is the correct value for HDA spec 3.3.2, register offset 00h,
bits 12-15 (Number of Output Streams Supported (OSS)), which is 0x00 (no audio
output streams) on the AMD cards for some reason.

For Christian's card the correct value seems to be 4, but I wonder if the same
is true for 6/7-pin cards as well or if they have it at least 6/7 so there are
streams for every pin available. If (streams >= pins) is true always, I think
there is no need to add any other fixes.
