Mpv crashes when Windows switches audio channels/config.

Important Information

• mpv version: 0.34.0-325-g602995fd40 Copyright © 2000-2022 mpv/MPlayer/mplayer2 projects (built on Sun Jun 12 12:22:05 2022)
• Windows Version: Windows 10 Pro 20H2 v19042.985
• Source of the mpv binary: https://sourceforge.net/projects/mpv-player-windows/files
• If known which version of mpv introduced the problem: Don't know, but In version '0.22.0-git-1d4273c (C) 2000-2016 mpv/MPlayer/mplayer2 projects (built on Sun Nov 20 18:59:12 CET 2016)', the error was not present.
• update: version 0.32.0-645-g7f67c5250a Copyright © 2000-2020 mpv/MPlayer/mplayer2 projects (built on Sun Aug 16 15:31:30 +08 2020), works fine (log below)
• update2: after trying many files, the last working version for me is 0.32.0-690-gbb1f821078
• from 0.32.0-713-gf57b90b069 starts failing.

Reproduction steps

My PC is connected via HDMI (from GTX 1080) to and audio receiver (Yamaha RX-V385). It tunnels my video and audio to get 24bit 192khz and 5 channels support.
I don't turn off my PC at night, but I turn off monitors/audio. When I do that, the audio channel of Windows switches to 2.0 48khz. I expect mpv to switch audio channels too.

Actual behavior

Mpv doesn't switch audio channels and crashes. No error msg on screen, just closes by itself. There is an error in the log file. It's annoying because If I pause a video, go to sleep, and want to continue watching it the next day, I have to re open it and manual seek where I left off. It's ok if It loses audio focus, I just want to avoid the crash.

Start with the ao/wasapi audio-output path indicated by the logs and compare behavior between the reported working and failing versions. Reproduce a Windows audio-device channel/configuration change while playback is paused, focusing on the AUDCLNT_E_UNSUPPORTED_FORMAT failure and subsequent crash. Done means mpv does not close unexpectedly when the device changes.
