I got new DAC recently (RME ADI 2 on USB) and I tried it with MPC Audio Renderer, but the WASAPI exclusive mode is causing stuttering in movie playback. No problems in shared mode or with other audio renderer, but then the sample rate is obviously not auto switched. How is the WASAPI implemented in MPC? Push mode or event mode? For example in foobar this DAC has problems in event mode but push mode works OK. I also tried various settings in MPC Audio Renderer including buffer sizes but it always stutters in exclusive mode with any content no matter what.

Then I tried Sanear Audio Renderer from GitHub and it works without any problems in WASAPI exclusive mode with this DAC, including auto sample rate switching. No hiccups whatsoever. But I really would like to use the internal MPC Audio Renderer - can this be fixed? I am on win10 x64 1909, MPC x64 1.5.4.
