--- Comment #13 from Andrew Eikum aeikum@codeweavers.com 2013-01-15 09:10:38 CST --- No, winecfg uses the winmm API, not dsound. winmm doesn't have to do any mixing, so it doesn't attempt to use the preferred mmdevapi format. It just feeds the WAV data directly(-ish) to mmdevapi, so it doesn't matter that mmdevapi was reporting a bogus preferred format.
