No in game sounds on Apple TV

I have an Apple TV HD, model A1625, 32GB running latest tvOS 14.7 (18M60), and for the last two Zwift app updates, I have to restart the Apple TV box to be able to hear the starting music and in-game sounds when using Zwift. One thing I have noticed is that after a Apple TV restart the Zwift app takes several seconds to start. If I exit Zwift, and restart the app, then it loads up almost immediately, but no music or other sounds. It’s a minor annoyance, but it would be nice to get a fix.
