AppleTV Audio Dropouts
I use multiple streaming devices on multiple TVs and Apple TV (multiple versions) is the ONLY device that has 1-2 second audio dropouts, especially during commercials between the various ads.
I am not the only one who has complained about this issue, which is your device, and it never seems to be resolved. Or, one of your techs asks a litany of useless questions about cables, etc. I am IT professional adept at troubleshooting. The problem is YOUR device.
You have a software problem that I wish you would address, otherwise I will simply replace all my AppleTVs with Roku, which doesn't have the issue.
I just loaded the most recent software 17.6 - same issue.
