But, if I then unplug the HDMI and plug it back it, the problems return.
The only solution I've found so far is to put the computer to sleep and wake it again while the HDMI is connected, and then the audio goes to my TV as expected and playback speed goes back to normal - this also works with restarting the laptop with HDMI connected. When I change the audio output device to HDMI though, no audio goes through and playing any video/audio file has a weird bug where playback speed is like 10-20 faster than normal. When I connect the HDMI from my laptop to my TV, the display works perfectly.
I've had Windows on this laptop for a few years, but recently have been having issues getting audio to play on my TV when connected with an HDMI cable note: the 2015 Macbook has a regular HDMI port, so there is no display port adapter in play here. Hi, I'm running Windows 10 on my Macbook Pro 2015, installed via Bootcamp.
