Virtual Surround add-on resets audio output back to hardware default after reboot

Kodi Add-ons
1

Device: Amlogic S905X4 running CoreELEC 22
Add-on: service.virtualsurround with custom virtual ALSA device VirtualSurround_TV

The add-on can create the virtual audio device correctly, and playback works fine if I pick it manually in Kodi audio settings.

But every time I restart the add-on or reboot the box, the audio output gets reset to the hardware ALSA default device automatically. Logs show the add-on runs a built-in function to save the default hardware device and overwrites my custom setting.

I have tried disabling Kodi auto audio switch and using advancedsettings.xml to lock the virtual device, but the add-on’s internal save logic still overrides my config.

Could we add an option to stop this forced default device overwriting, or let the add-on set its own virtual device as the persistent default automatically?
This would make the virtual surround feature usable across reboots without manual reconfiguration each time.

What is your default audio device in bluetooth settings?

This was the base default device for me.

I’m working on a virtual surround sound plugin that relies on alsa-lib. I’m currently using version 1.2.11, and upgrading to 1.2.16 should fix my issue.

Hi, is service.virtualsurround publicly available? I couldn’t find a repository or ZIP. Is there a beta version I can test?
