Audio playing problem

Anki Desktop
4

Thanks @dae

@congbosun I’m just an average mpv user for the most part who just uses mpv as a default video and audio player and happened to know a bit of coding. There were a number of changes to mpv in Anki 2.1.29 that I’m responsible for, but they were supposed to improve and add support for Windows and not break anything.

Once you start Anki, try to open the Debug Console (https://docs.ankiweb.net/#/misc?id=debug-console), copy-paste the following code and press Cmd+Return. Then close the Debug Console window and review your cards as usual. Once the audio can’t be played, please wait about 5 seconds and try to click the audio play button a few times. Then close Anki and upload somewhere mpv.log.txt from your Desktop, e.g. on https://gofile.io.

import aqt.sound

aqt.sound.mpvManager.shutdown()
aqt.sound.mpvManager = MpvManager(mw.pm.base)
path = os.path.expanduser("~/Desktop/mpv.log.txt")
aqt.sound.mpvManager.set_property("log-file", path)
av_player.players[0] = aqt.sound.mpvManager

print(path)
print('Done!')

The code contains a couple of additional log messages that maybe will help to narrow the issue down and eventually fix it.
