Currently watching the Rangers PSV match on BT SPORT 1 through the app on Fire Stick 4K Max, and getting constant audio glitching every 15 - 20sec's of what sounds like a momentary loss of audio before it returns (Bit like a skipping CD but faster)
EDIT:
Also getting this on Apple TV 4K too
Devices connected to TV; not getting this problem on other services or channels
Watching the same match via Edge browser on Windows 11 getting the same audio glitching have no other problems. Just glitching on the BT stream. Also glitching on the Windows App
Getting more audio glitching on BT SPORT 3 (Chelsea Vs Salzburg)
Both Chromecast and Apple TV 4K
