I have connected my Mac to my TV screen via an HDMI cable.
For several months, I have been able to watch TV with sound, by starting a video on the Mac, then connecting the HDMI cable to the TV. But for some reason, that won’t work anymore.
I'm having what seems like a common problem - namely, the picture is fine, but there's no sound.
I've researched all over, and none of the suggested remedies work.
System Preferences/Sound/Output just shows ‘headphones’ but does not show any other options.
System Information/Hardware/Audio : shows ‘Built in Output’ with a headphone image. HDMI is not listed as an option.
Display: Optimize for iMac, or 42 TV.
I have tried both these options, sound still doesn’t work.
Is there some kind of switching device I could get to make sure I don’t have this issue?
Any ideas? Many thanks!
