Can’t get mic to work in VATSIM

Like the title says I can’t get my mic to work with VATSIM. I dial my radios to the correct frequencies and can hear people but no one can hear me when I try to talk. I’ve tried changing mics and changing my PTT button and nothing seems to work. When I configure my audio setting the bar for the mic increases when I talk into my mic so it’s obviously receiving the input but it won’t work in game for whatever reason. It seems like maybe a PTT issue. Any help would be appreciated.

Which client? If applicable, have you tried the troubleshooting steps in your client’s FAQ and Troubleshooting guide, and what were the results?

Also, you posted this in General Support, but did you check/search the support forum for your client?
