Apple TV - Volume control issues

Update to the above post:

Today, when I turned on the Apple TV, the sound level was at "0" (no sound). I was able to raise the volume, (numbers increasing) however, as soon as I let go of the volume up control, the volume immediately went back to zero (no sound).

Again, the TV, Soundbar, and FireStick work perfectly. It seems to be turning out that the Apple TV is a poor replacement for the FireStick.

Any help in resolving this would be greatly appreciated.

Update - February 2024

It turns out that the remote was defective, however, it took a bit to get there. After a number of lengthy diagnostic sessions, Apple acknowledged that the unit may be defective.

The Apple TV unit, was replaced under warranty, however, they did not want the remote. The new Apple TV had the same problems, and with another lengthy diagnostic session, Apple acknowledged that the remote may also be defective.

With the new remote, the Apple TV now works properly.

All together, it took multiple phone calls, diagnostic sessions, and two device shipments to get it working.

Thank you for your response.

We tried re-pairing, resetting the box, restarting, basically everything. I was on the phone about three hours over several days in diagnostic sessions. we repeated all of the steps multiple times with the same results each time.

Eventually, I guess Apple got tired of me calling and replaced the box, and eventually the remote.

I still have some weird sound issues - some channels are normal with the sound level at 18-20, while other channels need to be up at 45-60. It is a nuisance, especially when changing from a soft channel to a regular channel and forgetting to change the volume back to normal before changing the channel.

In all fairness, the Apple TV is much faster than the Firestick.
