Audio output does not switch after first Bluetooth device disconnects

Hi,

I have been experiencing an irksome issue with the audio output for a few days now after the last updates, some by Dell software that was factory installed when I received my laptop, and the latest Windows 11 update.

All of that was installed five or six days ago.

Since then, what happens right after a reboot is this:

• By default, sound comes from the internal speakers.
• If I plug an audio jack, sound comes from the internal speakers, as if nothing has been plugged in.
• If I connect some a headset or earplugs wirelessly via Bluetooth, the sound output is switched to the said headset or earplugs.
• If I ever turn off the said headset or earplugs, I will no longer be able to have sound output other than the internal speakers, be it the same device that was previously connected or not: any Bluetooth device will appear connected, the sound icon in the system tray will say that the sound output is now the Bluetooth device, but sound will actually come out of the internal speakers.

The only way for me to have sound output through a device is to reboot the laptop. I have tried:

• restarting the Bluetooth service,
• switching the output device manually to the connected device,
• uninstalling MaxxAudio Pro (which had had no useful effect in my eyes),
• looking for an error of any kind in the Event Viewer. 

None of this helped me sort it out.

Is anyone else encountering this same issue? Does someone have an idea as to what is causing this and how to solve it? 

Thanks.
