Q: Headpone port not working with hdmi connected

After updating to macOS Sierra the headphone port on my mac mini (mid 2010) will not work with my display connected over hdmi. I have selected the headphone port as output device in the menu, but there is only silence. If I remove the hdmi cable I get audio over the headphone port. I'm guessing there is some kind of bug with audio over hdmi that causes this. Is there any way to deactivate hdmi as an audio output device so it just defaults to the headphone port? Or some kind of other workaround?

best regards
Martin

Mac mini, macOS Sierra (10.12)

Reset the SMC, as per > Reset the System Management Controller (SMC) on your Mac - Apple Support
and then the NVRAM, as per > How to Reset NVRAM on your Mac - Apple Support

Try switching the sound output in System Preferences > Sound > Output
and then also from Applications > Utilities > Audio MIDI Setup.

Hello, I did the steps you, but there were no change. Ended up getting a miniDP to DVI adaptor and connecting my monitor that way so now it is working. Thanks for the suggestions.

That is one way a great way to fix the sound output to HDMI problem.

FWIW I've always only used a DVI or dual DVI monitor setup with my 2010 and 2012 Mac Mini's.
