Do you have a screen protector on your phone? If so, it is likely interfering with the proximity detector.

No screen protector on the phone. It just goes black as soon as I click play or answer phone call and won't go back to screen till once I've hung up

Then there is most likely something wrong with the proximity detector. There are numerous free apps you can install to test the sensor: https://play.google.com/store/apps/...RQKEnByb3hpbWl0eSBkZXRlY3Rvcg==:S:ANO1ljKVsTw

The odd thing is that the screen is blanking out when playing media. The proximity sensor should only be blanking the screen when you're on a call and then block the proximity sensor.

Does this happen in Safe Mode as well? https://support.google.com/nexus/answer/7665064?hl=en
