Expected Behavior

When the audio monitoring device is changed after being removed (etc if a display was disconnected and reconnected) all sources set to monitor and output should still send audio to the monitored device.

Current Behavior

When the audio monitoring device is changed after being removed (etc if a display was disconnected and reconnected) all sources set to monitor do not send any sound to the monitor device. This can be fixed by selecting monitor off and then reselecting monitor and output on each source individually.

Steps to Reproduce

1. Set up audio monitoring with a device and a source.
2. Disconnect that device (remove HDMI) when obs is closed. (Note: The problem does not occur if the audio monitor has been replugged in before obs is started for the first time after a boot.)
3. Reconnect the device and open obs.
4. Attempt to monitor audio from a media source or audio input.

Anything else we should know?

This is a common issue among users that is still yet to be fixed.

FWIW, here's a simple python script to reset the monitoring on all media sources: fixmonitor.txt

Rename to fixmonitor.py, make sure you have obsws-python installed, and run it. Scripting-wise it's pretty ugly, but should be functional (use at your own risk, of course). Assumes obs-websocket is running on port 4455 on the local host, without a password. On a non-windows system, remove the two lines mentioning msvcrt.

Thank you this works well, I have also found that if you exit OBS without changing any settings then reconnect the monitor device and restart OBS the problem resolves, but it would still be nice if this didn't need to happen at all.
