--- Comment #14 from Michael Stefaniuc <mstefani at redhat.com> ---
The proposed patch is incorrect. DSBCAPS_CTRL3D does not imply DSBCAPS_CTRLPAN.
Quite the opposite, the two flags are mutually exclusive. The code and comment
are actually correct but just for secondary IDirectSoundBuffer8.

On the other hand error checking in version 1 is incomplete. Native allows both
to create a 3D secondary buffer with both DSBCAPS_CTRL3D and DSBCAPS_CTRLPAN
set as well as calling SetPan() for such a buffer. The associated GetPan() on
the other hand fails with DSERR_CONTROLUNAVAIL.

I have submitted a fix for this with tests:
