Install the Media Feature Pack if applicable.

Does it still happen in a new profile? An easy way to test a new profile is to install Developer Edition and see if it happens there or refresh your existing profile.

I tried creating a new firefox profile and the issue persists, same with developer edition. Media feature pack not found under optional features, closest is windows media player which is already installed.

All drivers are up to date and issue persists on different audio devices.

You can test older Firefox versions with mozregression to see if this is a recent breakage and identify when it first appeared.

Still unsolved, does anyone know what could be the cause?
