[Core V31 - front audio panel]

Hey,
I have a problem with the audio port on the front panel. When I plug in headphones, sometimes it does not recognize that headphones are connected or it starts to change state in the system, that it is connected and disconnected alternately. When I push Jack down a bit, it connects well.

I wrote to support in Germany (a month ago), I wrote to the information (2 weeks ago) and filled out the support application form (a week ago) and still no answer.

Does anyone know if such an audio panel I can buy somewhere?
