Multiple prior reports. Search the forum for tvOS 15, iOS 15, etc to find them.

Playing videos with Stereo MP3 has no Audio in tvOS 15 beta

Also happening with other audio formats. There are multiple threads on the topic. iPhones/iPads are exhibiting similar issues with iOS 15 beta. Second thread below mentions a possible workaround, forcing a transcode.
