I was really wanting to like this card. I bought the Taichi to put in my Taichi motherboard. Gaming is great and after a slight undervolt it runs cool. Big problem is AMD drivers. Our PC is our media center hooked to our TV via HDMI. The 5700xt drops audio periodically. The old 580 had no problems. Wish I had payed a bit more for the 2070 super. If you need HDMI don't buy.
I would never use audio over HDMI myself (I'm an audio snob and use optical to 5.1 external stereo setup) ... Maybe check if your TV has optical in (s/pidf), and check if your onboard audio on your mobo has optical out - then use that instead. Optical cables are thin, light and inexpensive and the sound quality will be better.
If not ... in the mean time until this gets fixed ...
Try keeping the GPU a bit busy while watching TV (a light game idle in the background should do the trick - turn vsync and Chill on to cap framerate to keep fans from spinning up too much) --- the issue seems to be related to an idle GPU (from some quick checking ...) -- which is why games don't have the same problem.
I think you have an x570 board? Maybe also try the card in PCIe 3.0 mode from the bios.
Keep checking for driver updates; there's a major one coming out soon ... not many people are having this problem, but I can see how it would be a major pain if HDMI is your only audio option ...
