English Amiga Board - View Single Post - Click/buzzing on un-pausing with WASAPI (EX) audio

I noticed a small audio problem which seems happen on (un)pausing emulation. Testing on Windows 10 1709 with audio via AMD graphics card DisplayPort. Using A500-like cycle-exact config, Corruption (Magnetic Scrolls) ADF. It seems to happen only with WASAPI (EX) sound.

If "Automatic switching" is enabled, there is a click every time you un-pause. Sometimes on un-pausing there is a constant buzzing, as if the same buffer content is output over and over. Larger buffer size settings give a lower-pitch buzzing. Once the buzzing starts, it remains as you repeatedly un-pause.

When "Automatic switching" is not enabled, there is a click sound each time you un-pause by pressing the Pause key, but no buzzing as far as I could tell.

If you change to WASAPI shared, un-pausing a few times after that gives a click, but the clicks stop after a few times.
