Constant Headset issues, do I need a new cable?

[razgour]

I bought a Vive Pro HMD in March 2020 as an upgrade for my original Vive headset. It immediately gave me trouble in the form of the right ear-phone not playing audio. On this forum I found a tip for tightening the screw for it and this seemed to help a bit, but I really just didn't have time to play it much (I just had a baby) so I let it sit. In retrospect I should have tried to send it back for support back then but as I said I was pretty busy.

Over the last few months I've started using the headset regularly again and the issue seems to have gotten worse, the audio will only work if the the eye-piece is slid forward part-way to an exact location. If I slide it fully towards my eyes or fully away audio will cut out on the right ear-phone again. I've also noticed that the eye-distance adjuster knob doesn't do anything. If I spin it it will bring up the eye-distance numbers momentarily but then they will disappear without adjusting. Sometimes when the audio doesn't work at all no matter how I adjust it if I pull out the data cable from the headset and REALLY push it back in hard it will start working again.

I'm wondering if this is something likely to be fixed by a new cable? They aren't cheap but I'd absolutely buy one if it resolved this. As it is it's actually not a great experience even when it is working with the eye-piece slid out a distance as it throws off my peripheral accuracy. I was a very early adopter of the Vive and would like to stay with the product line as I upgrade through the years, but this one glitchy headset is starting to sour me on the name.
