Stuttering Sound When I Plug Macbook Pro M1 (14-inch, 2021) into TV via HDMI

Mine just started doing this on the last OS update to Ventura. It was working ok with the prior OS. The lame fix to plug in the HDMI cable then restart the computer did work for me today. Not fun to reboot your computer for something simple like this.

Hello SpencerH27,

Thank you for reaching out to Apple Support Communities, and we'll be happy to help in any way we can. We understand you're having issues with the connection from your Mac to your TV. To start, see if the steps lsited here help resolve the issue: Connect to HDMI from your Mac - Apple Support

"Check if you need an adapter

Mac computers that have any of the following ports can connect to HDMI devices:

• If your Mac has an HDMI port, you can connect directly to HDMI with an HDMI cable.
• If your Mac has USB-C ports, you can connect to HDMI with an adapter, like the Apple USB-C Digital AV Multiport Adapter.
• If your Mac has Mini DisplayPort, you can connect to HDMI with a Mini DisplayPort to HDMI adapter or cable.

Check specifications

Mac computers that have a built-in HDMI port comply with HDMI 1.4 or later and support:

• Up to 4K at 60Hz on compatible Mac models.
• Up to 4K at 30Hz on compatible Mac models.
• 8-channel/24-bit audio at 192kHz, Dolby Surround 5.1, and traditional stereo.
• HDCP-encrypted playback from iTunes and QuickTime Player (version 10). Safari in macOS Sierra or later also supports HDCP-encrypted playback, if the web page is HTML5-enabled and the content is FairPlay Streaming-enabled and delivered using Media Source Extensions or HTTP Live Streaming. To play HDCP content on an external display, HDCP playback requires an HDCP compatible display.
• HDR on compatible Mac models.

If using an adapter, check the specifications of the adapter to learn about supported resolutions and other details.

Up to 4K at 60Hz

You can connect a display with a resolution up to 4K at 60Hz to the HDMI port on these Mac models: 

• Mac Studio introduced in 2022
• Mac mini introduced in 2018 or later
• Mac Pro introduced in 2019
• MacBook Pro introduced in 2021

Up to 4K at 30Hz

You can connect a display with a resolution up to 4K at 30Hz to the HDMI port on these Mac models: 

• Mac mini introduced in 2012 through 2014
• Mac Pro introduced in 2013
• MacBook Pro introduced in 2012 through 2015

If your display isn't recognized

If your Mac doesn't recognize your HDTV, display, or other HDMI device after making the connection:

1. Turn off the HDMI device while your Mac is turned on. 
2. Unplug the HDMI cable from your Mac, then plug it in again.
3. Turn on the HDMI device.

If your display isn't showing the whole picture

If the video on your HDTV or display extends beyond the borders of the screen, press Option-F1 on your keyboard to open Displays preferences, then adjust the Underscan slider* for a better fit.

If your Mac goes to sleep while a video is playing or paused, you might see an HDCP error. Quit the app that is playing the video, then open the app again. If the issue continues, choose Apple menu > System Preferences, then click Energy Saver and adjust the settings so that your display doesn't turn off.

* The Underscan slider appears for only some configurations and resolutions.

If your HDMI device isn't receiving audio

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

• Choose Apple menu > System Preferences, then click Sound. In the Output pane, make sure that your HDMI device is selected.
• If you're connecting using a Mini DisplayPort adapter, make sure that your Mac can send audio over Mini DisplayPort.
• If you're connecting from a Mac mini, unplug any audio device that is plugged into your computer's Audio-Out port.

Mac computers don't support using CEC (Consumer Electronics Control) to control HDMI devices."

We hope this helps.

Cheers!
