Unmute button broken

updated to latest today, and the unmute key doesn’t seem to work for some reason. I read in the update announcement that there was some change where increasing the audio on mute will unmute the device, and that happens fine, but if I mute the laptop and use the key unmute, it only changes the tooltip text on the taskbar audio icon, but doesn’t actually unmute the device.
Any help is appreciated, tia!
