Do conversion directly, using the infrastructure that was added before. This also rewrites part of format negotation, I guess. I couldn't test the format that was used for S24 - my hardware does not report support for it. So I commented it, as it could be buggy. Testing this with the wasapi_formats[] entry for 24/24 uncommented would be appreciated.
