Pulseaudio breaks wine dsound tests

[austin987]

Wine's conformance tests break when pulseaudio is running:

ds3d.c:1225: *** Testing Primary Sound Driver - ***
ds3d.c:1239: Testing the primary buffer
ds3d.c:449: Test failed: buffer size changed after SetFormat() - previous size was 88200, current size is 22052
ds3d.c:1242: Testing 3D primary buffer
ds3d.c:449: Test failed: buffer size changed after SetFormat() - previous size was 88200, current size is 22052
ds3d.c:1245: Testing 3D primary buffer with listener
ds3d.c:449: Test failed: buffer size changed after SetFormat() - previous size was 88200, current size is 22052
ds3d.c:1225: *** Testing default - winealsa.drv ***
ds3d.c:1239: Testing the primary buffer
ds3d.c:449: Test failed: buffer size changed after SetFormat() - previous size was 88200, current size is 22052
ds3d.c:1242: Testing 3D primary buffer
ds3d.c:449: Test failed: buffer size changed after SetFormat() - previous size was 88200, current size is 22052
ds3d.c:1245: Testing 3D primary buffer with listener
ds3d.c:449: Test failed: buffer size changed after SetFormat() - previous size was 88200, current size is 22052
ds3d: 865 tests executed (0 marked as todo, 6 failures), 0 skipped.

Running the tests without pulseaudio works fine, of course.
