I may be late to the party on this issue, but I can't locate much by way of a solution. I'd been playing everything from my Apple TV (generation 3) to the Home Pod without incident until about three days ago where suddenly no sound comes through at all. I've restarted, reset, reloaded, etc., etc., but to no avail. I have been looking forward to purchasing a second to take advantage of the stereo-syncing capability for my home theatre — and it's more than enough quality for me because I have hearing loss enough to, for better or for worse, be unaware of the audial nuances people with their full hearing faculties enjoy. Such is life. Any insight would be appreciated.
