After updating to TvOS 17, my Sonos Beam sound bar started making weird crackling sounds and music sounded tinny. Turns out, I had to change the audio format in the Apple TV settings from Stereo to Dolby Digital 5.1 for the issue to be fixed.

Not sure what I had that setting set to before but I’m leaning toward the idea that the update reset the audio format back to default settings. If you are having sound issues after updating, that might be the issue.
