Topic: Weird TV audio issue.

So I got a new TV over Christmas and I have noticed something really weird. When using the TV speakers, on the Switch home menu only, and again, only using the TV speakers (not my external sound system) the audio fades in and out. As far as I can tell, this only happens on the home menu.

I know it's a bit of a questionable Chinese TV from Hisense and I am using my sound system anyway, which doesn't have the issue, even though I am running the audio through the same TV.

Anyone have any idea why this might be happening? I am more curious than anything else.

For reference, I could not replicate the issue in games, or with my PS4 or PC.
