Happens in Exclusive mode on my living room computer (Realteak Coax output) with Denon receiver.
24 bit 44.1 khz 2channels is supported (tested in mixer)
However it gets resampled to 32 bits and sound is distorted.
(Probably due to soundcard or receiver not supporting 32 bits for this samplerate? Even though Wasapirenderer seems to think so)
