winealsa: improve sound quality for IDsDriverImpl

[Sylvain Petreolle]

Hi Jerry,

With your patch applied,
I get a write access to a NULL pointer when trying to get sound with
dsound (winmm tests are running ok.)

Since I was using precompiled RPMs from freshrpms.net when doing the
first try,
I switched to 0.9.7 sources. Same result.

I attached a trace from a run of
wine dsound_test.exe.so dsound --debugmsg +wave,+dsound,+dsound3d

Could you have a look on this ?
