Aspire 7720G broke front audio panel

I damaged the front panel audio connector and now it doesn't runt off internal speakers when connecting headphones and similar devices.

Is 55.AHJ02.002 correct part number for the spare part?
Here's the image of what I did:

 

OMG what did you do to that poor port?

But yes looking at the service manual you are a lucky SOOB and they are on a separate board and not soldered onto the motherboard as usual.

It also looks like that is the right part number.

 

Thanks a lot! I couldn't find the service manual to confirm the part number.

The story behind the port is a bit complicated. It has a plastic ring on the outside which over time cracked at the point where it connects to the board. Apparently that's because I often use 3.5 mm TRS to RCA connector adapters and the fact that laptops s at the edge of my desk, so the adapter keeps moving a bit and the movement over time cracked the ring.

Then last night, my chair hit one of those adapters and forcibly removed it form the receptacle. The tip of the adapter stayed inside. To reach it, I had to remove the cracked plastic ring. After lots of problems I managed to remove the tip, but I couldn't put back the plastic ring. The receptacle is working fine now without the ring, but the jack isn't connected very securely, so to me it looks like the best idea is to replace the whole board, since it's not too expensive.
