Since upgrading last week my phones no longer work. and at times my hdmi display turns blue. but I just remove the hdmi port and plug it back in and its good. but the headphones no longer work though. tried to toggle back and fort to no avail.

Hi there-about all i can suggest to you now is zap the pram and reset the smc, how to do that can be found on the support section of apple’s website, or use google. If you hold down the option key and click on the speaker icon at the top right of your screen, you’ll see a list of all available sound inputs and outputs. Running audio midi app would be helpful as well
Hope this helps
