Description Of Issue
When I try to use DSP, procedural EQ, Mix, and no other DSP, and play MQA from Tidal, I get an erorr message ‘Unexpected error communicating with audio device’. From the logs, the below appears
10/28 22:00:37 Warn: [zoneplayer] failed to start stream System.ArgumentException: only supports 2ch content

This does not happen(ie it works fine) if I play a non MQA track, but fails with every MQA track I try. If I turn the DSP off, there is also no error playing any MQA tracks.
I have tried MQA Renderer only and MQA Decoder and Renderer and also downmixing and Channel mapping on the device setup, but all combinations fail the same.
Please advise. Thank you
