[BUG] Internal player freezes when sound output changes

[fvannee]

Describe the bug Race Control freezes/crashes when internal player is playing and sound output changes from speaker to just-connected Bluetooth headset.

To Reproduce Steps to reproduce the behavior:

1. Play a stream with internal player
2. Connect a Bluetooth headset (not sure if it's relevant that it's Bluetooth or not - could well be the case that any change in sound output device triggers this)
3. The stream freezes and becomes unresponsive

Expected behavior Sound output changes from speakers to headset

Desktop (please complete the following information):

• v2.3.3 on Windows

Additional context Couldn't find anything interesting in the .log file when it occurs

For me the stream does not actually freeze when connecting a BT headset, but it does not transfer the audio to it. I have to close the feed and open it again. This is happening when I just use the watch button to watch the stream. I think that would be the internal player.

If this is something you want to fix @robvdpol, I can have a look at it if you want.

@robvdpol @fvannee The issue might be in Flyleaf, I have created this issue there to track it.

I got the problem but it worked fine last week. Any Windows Update that cause this problem?
