Yep, same issue here and cannot find a fix for this at all. Have done everything that I can possibly think of.
My issue is a little bit different though, I get sound while wired but mic does not work at all, but sound and mic while dongled. However, I cannot hear anybody in discord for example if I am using the dongle, but they can hear my because my mic is working. Its like I can either hear other people but cannot speak in discord, or speak and not hear. There is no middle ground.
