I have an audio issue for which I need knowledgeable assistance? Where could I find a consultant who knows Fedora, KDE, and optimally but not necessarilyMicrosoft Teams?

My setup used to work, and now it doesn't. There are too many moving parts for me to diagnose, particularly as I am new to Linux.

My Jabra Evolve2 40 headphones are plugged in to a Lenovo P1 Gen 3 USB-C port. The KDE audio profile for the headphones has set to Pro Audio, and I also tried Digital Output. There is no sound through the headphones. If I unplug the headphones, then there is sound through the on-board speakers. Just not through the Jabra headset.

This needs to work, so I need to hire someone who can make it work. What are some good boards on which to post this for a consultant to respond?

And, of course, if anyone here knows the answer (or wants to work on it), please lmk!
