Thanks. Your log says:

84921.201:00ac:warn:xaudio2:IXAudio2Impl_CreateSourceVoice OpenAL can't use
this format and no FFmpeg, so giving up

Whoever built your Wine didn't have ffmpeg available at build time (or the
changes to configure.ac are buggy).

It does show a bug, though. We should be returning AUDCLNT_E_UNSUPPORTED_FORMAT
instead of "successfully" creating the voice with a format we can't handle.
