no speakers showing in audio settings for macbook pro

That's why it works with headphones or external analog speakers.I have tried all the fixes i could find but for some reason.no audio will go into OBS.my audio works on audition and Audacity. When it gets stuck and nothing is in there, it thinks an optical cable is plugged in since the switch is down but nothing conductive is in there. If the switch is pressed down, the computer checks to see if the plug inside is metal or plastic based on conductivity.

If it's optical, the end is made of plastic. If it's an analog cable, the end is made of metal.

When you stick in an audio cable, it pushes the switch down. The problem is actually caused by a little switch inside the jack that gets stuck. Taking a toothpick and fiddling around inside the jack has solved the problem for some, you should try this. The internal speaker option will come on if the switch is unstuck. Plug the speaker jack in and out several times while watching the Sound-output system preference panel. There is switch inside the jack that is stuck.

There is a thread here, which has some possible fixes. If yes, then you have Digital Out on, and this messes with the speaker configuration.

If you look in your headphones jack, is there a red light on?
