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
