MacBook audio not working through HDMI on TV

Here’s how you can fix the audio issue when connecting your MacBook to your TV via HDMI:

1. Check Audio Output Settings:

• • Go to System Settings > Sound > Output.
  • Select your Toshiba TV from the list of devices.

1. Check Volume on TV:

• • Ensure the TV's volume isn't muted or turned down.

1. Restart Devices:

• • Disconnect the HDMI cable, restart both your MacBook and TV, then reconnect.

1. Ensure HDMI Carries Audio:

• • Some HDMI cables only carry video. Try using a different HDMI cable to ensure it supports audio.

1. Reset NVRAM/PRAM:

• • Shut down your MacBook.
  • Turn it on and immediately press and hold Option + Command + P + R until you hear the startup sound twice.
  • Check if audio works after restarting.

1. Update macOS:

• • Ensure macOS is updated to the latest version, as some HDMI issues are fixed in updates.

1. Test with Another TV or Device:

• • Connect your MacBook to a different TV or monitor to rule out issues with the TV itself.

If none of these work, it could be a compatibility issue with your TV. Let me know if you need more help!

If your MacBook’s audio isn’t working through HDMI on your Toshiba TV, here are some steps to troubleshoot the issue:

1. Check HDMI connection: Ensure the HDMI cable is securely connected to both your MacBook and the TV. Try a different cable if possible.

2. Set the audio output device:

• Go to System Settings > Sound > Output.

• Select your TV or HDMI as the output device. If it doesn’t appear, disconnect and reconnect the cable.

3. Check the TV settings: Ensure the TV is set to the correct input source and that the audio isn’t muted.

4. Restart both devices: Restart your MacBook and TV, then reconnect them.

5. Reset PRAM/NVRAM on MacBook:

• Shut down your MacBook.

• Turn it on and immediately press and hold Option + Command + P + R for about 20 seconds.

• Release the keys and check if the issue is resolved.

6. Test with another TV or device: To determine if the issue is with the MacBook, HDMI cable, or TV, test the connection on another TV or use another device.

7. Update macOS: Ensure your MacBook is running the latest macOS version by going to System Settings > General > Software Update.

8. Reset SMC (for Intel-based Macs):

• Shut down your MacBook.

• Hold Shift + Control + Option on the left side of the keyboard, then press the power button for 10 seconds.

• Release all keys and turn the MacBook back on.

If none of these steps work, there may be an issue with the HDMI port, cable, or software configuration. Consider contacting Apple Support or visiting an Apple Store for further assistance.

I hope this helps!

are you selecting your TV in the menubar sound options? (my tv is labelled "SAMSUNG")

and in my case, whenever the TV is selected, the volume on the mac's end is showed as "maxed out". I can only control the volume on the TV's end.
