MacBook Pro M1 HDMI to HDMI or USB C to HDMI outputting stuttered sound on TV

I had this issue with my MacBook Air M1 yesterday. Seems to be a software issue. There is a temporary fix. (MacBook Pro M1 2020 Skipping Video/Audio … - Apple Community)

1. Connect Macbook to the external monitor/tv with HDMI.
2. Set external sound to the monitor/tv.
3. Restart the computer.

Yes, you have to do this every time you want to use the HDMI until a software update in the future fixes this.

I have a Macbook Pro M1 running Sonoma 14.4.1. I have used this for over a year with a tv via HDMI with no issues. In the past two days, the audio glitches dramatically, skipping ahead several seconds relative to the corresponding video. Eventually the audio cuts out and the video may speed up unbidden (to catch up?) or otherwise glitch out. Videos play fine on the laptop itself and when casting video wirelessly - they only glitch when played to a TV via HDMI.

to avoid debugging issues that Apple has already seen and solved, update to the latest MacOS, which may include fixes for issues like this.

Grant, Sonoma 14.4.1 *IS* the latest MacOS at time of writing. If anything it (re?)introduced the problem.

So sorry, I am not seeing so well today. The trees are blooming and I am allergic. I read 14.1
