dsoundaudio: remove primary buffer
Enabling this option just creates a playback buffer with the specified settings, and then ignores it. It's probably some outdated hack to set audio formats on windows. (The first created stream dictates all other streams settings, at least on some Windows versions). Setting DAC_FIXED_SETTINGS should have the same effect as setting (the now removed) primary buffer.
