My helmet is bright red, and the speakers does not work, when I try to adjust the volume when there is no headset/speakers in, there is a sign of the cross as the symbol of the volume where the places are supposed to be, macbook pro retina display

My helmet is for some time, as the eye of the terminator, glowing and speakers have not worked since. I need to plug headphones or external speakers. Whenever I try to adjust the volume when it shows just a cross symbol under the sign of the volume, where small squares usually are (see below)

Is there a way to fix this? Some other similar forums tell me to try to manually move a switch in the audio jack, but I can't seem to find such a change and the thing that seems most like a light switch, does not move.

Can someone please help?

Thank you

Your audio output is stuck in optical mode, this is the red light.

The solution is to try to insert and remove the plug a dozen times or more in the hopes of convincing making fall out of optical mode and in electric mode.
