Hello m0j0riz3n,

Thank you for using Apple Support Communities. I can see that you're experiencing some issues with the audio options when connecting to the ports. You have done a great job trying to fix this on your own! I am happy to help.

Next let's reset the NVRAM, this part of the memory stores certain settings that can impact volume and sound. Please follow the following steps:

Shut down your Mac.

Locate the following keys on the keyboard: Command (⌘), Option, P, and R.

Turn on your Mac.

Press and hold the Command-Option-P-R keys immediately after you hear the startup sound.

Hold these keys until the computer restarts and you hear the startup sound for a second time.

Release the keys.

After resetting NVRAM, you may need to reconfigure settings for speaker volume, screen resolution, startup disk selection, and time zone information.

Have a wonderful day!
