Initialize COM using the multithreaded apartment
...
I honestly have no idea which is the correct (or better) mode to use given the
confusing mess COM is, but CoInitialize uses single-threaded apartments which
seems to be a problem for with at least a couple games in the STALKER series
(the call fails, which causes us to drop back to the DSound backend).

Reduce the gain of front-panned sounds with plain stereo

Now front-center sounds are attenuated by roughly -4.5dB instead of -3dB. This
will help keep rear-panned sounds from attenuating too much while not making
front-panned also attenuate too much.
