MacBook Pro M1 Max OSX Ventura having unusable intermittent audio video playback when using HDMI

HDMI cables you want for HDMI-only Displays (higher resolutions than 720p TV sets) are marked as Certified with an anti-counterfeiting tag and are labeled:

"Premium High Speed HDMI cable" or that + "with Ethernet" --OR--

"Ultra High Speed HDMI cable" or that + "48G"

Cables with No Certification tags are good for your standard 720p TV set, and not much more.

HDMI was invented for HD TV sets. it works great at its original resolution of 720i or 720p. At higher resolutions, it quickly develops issues that are complex to solve, and the cables and adapters required to solve are NOT intuitive.

More recent versions of MacOS are less tolerant, and tend to disconnect to flicker when the cabling is inadequate.

Hey Josja,

If this is happening on multiple devices and no solution has yet been discovered, and you've tested multiple cables as well, it might be best to Contact Apple Support from here for continued assistance.

Take care.

Hi Josja,

It seems like an HDMI device wasn't receiving audio when connected to your Mac, is that correct? If so, please check out this link, which has some information and suggestions that may help with that issue: Connect to HDMI from your Mac

If your HDMI device isn't receiving audio

If your HDMI device isn't receiving audio from your Mac:

* Choose Apple menu > System Settings (or System Preferences), then click Sound. In the Output pane, make sure that your HDMI device is selected.

* If you're connecting from a Mac mini, disconnect any audio device from your computer's headphone jack.

Thanks!
