Re: [PATCH 0/6] MR5870: mmdevapi: Implement loopback capture with winepulse backend.

[Paul Gofman (＠gofman)]

Fixes voice chat in Helldivers 2 (which works though PlayFab so it is probably going to affect more games once those pick that version).

I tested the real captured sound with a separate test program, attaching that just in case (it captures the sound card output for 5 sec and writes that to sound.wav).

I tried to incorporate test_capture() into the added test and, while that works perfectly on my real Win11 machine, that fails in a weird way on Testbot on Windows machines: IAudioClient_Start() never signals event and no data come through, that's across all the machines having sound card. I am guessing something doesn't work quite right with loopback capture in VMs.
