I'm on Linux with KDE and pulseaudio. I use DP for default audio output and plug my headset to the monitor.

It works well. But when I close and restart the monitor (or re-plug the DP cable), there's no sound from MC at all and it cannot recover automatically. KDE mixer and pavucontrol also show no MC in playback anymore.

Restarting MC or switching resource pack can help.

I tested Firefox and VLC player, and they can recover audio immediately after re-connecting audio device.
