Firefox makes system volume reduce to 50% when Tidal is playing music on Windows 10. I can see this happening through the system mixer, activated via the icon in the lower right hand corner of the screen. I am using a Steinberg UR22 mkII USB interface, but the behavior happens across all sound outputs. Going into the properties of the USB device have proved unsuccessful. Firefox does not trigger this behavior with other applications playing through the USB device. I'm wondering if there is some sort of setting left over from when I had Firefox Voice enabled? A fresh install of Firefox did not do the trick. This happens with all sound outputs on Windows 10, not just through the USB device. Does anyone have any ideas/solutions?
