I have my laptop hooked up to a monitor with built-in speakers via HDMI. Up until recently, the sound would always come through the monitor, but it just suddenly stopped, and it's coming through the laptop speakers instead. I checked the playback devices under sound, and the monitor isn't even an option anymore. Usually, whenever this happens, I just restart the computer, and the sound will go through the monitor again with the monitor showing up on the playback devices. I've tried showing disabled and disconnected devices, but still, it only shows my laptop speakers. I'm at a loss, and I have no idea how to get my sound to go through the monitor again. All of my drivers are updated, so that can't be the cause. It's really starting to piss me off, so if anyone out there has any suggestions or has gone through this before, have at it.
