Auto-Restart Audio Engine on Device Reconnect

This script (python3) will check all selected and available devices every 5 seconds to see whether devices previously disconnect were connected. If so the audio engine of Voicemeeter will be restarted.

Requirements

• Voicemeeter installed and running (supports VM, VM Banana, VM Potato)
• python3 and py available on the PATH

Setup

Copy files into the Voicemeeter install folder OR copy the VoicemeeterRemote64.dll into this folder so that the dll can be found by the script.

py

Running this as python directly will cause it to stop if Voicemeeter is not running or shutdown while it is running. As soon as it detects that, the script exits.

py autorestart-audio-engine.py

bat

You can chose to run the .bat file instead of the .py. This will then automatically restart the python script if it exits (5s later). Simply double click the .bat.

vbs

The .vbs file will start the .bat file once, but without a terminal window. Like this you can start the process in the background. This is especially helpful if you want to run this on Windows start.

Autostart on Windows

To enable autostart for this, press Win + R and enter shell:startup to open the Autostart folder of Windows. Place a link file to the .vbs file in that folder. To deactivate the autostart simply remove the link.

Stopping the process

You can stop the python process in the Task Manager. The return code should not be 0 and thus the .bat will stop as well.

If that does not work and your cmd window is hidden, you will have to search the Task Manager for the correct cmd.exe, stop that process and afterwards stop the python.exe related to the script.

Known Issues

py script exits if voicemeeter is not available

The script needs Voicemeeter to be running (Login status 0), because otherwise the selected devices can not be determined. If that's not the case the python script will simply exit because logout and login again did not work correctly. The .bat file will automatically restart it 5s after exit.

py script does not log out if the process is killed

It's not possible in Windows to gracefully interrupt and react on process kills. So if you're terminating the process from the Task Manager, it will not logout correctly. This means, that Voicemeeter will still detect the Remote Api connection and might block further logins if your limit is reached. Multiple restarts and kills will block multiple slots in VM.
