I am using PixelExperience_Plus_ginkgo-10.0-20201014-0012 on my redmi note 8 (ginkgo) with the latest android 10 firmware, the problem appears on that rom version, I have tried to update to the latest version and tried many other rom and yes the problem has been fixed , but the pixel experience plus version 10.0-20201014-0012 has the best performance and stability in certain games.Which ROM, device, firmware are you using? Is it a new issue or has the same problem occurred in other ROM's you have tried?
I have been compiling PE-11 for a while but it's a lot of new code going in at the moment, I'll look into it if you answer the above questions.
My problem with this ROM is only on the mic which cannot be used when using the zoom application and several other applications with non mic earphones.
Edit: Solved by changing the line vendor.audio.feature.compr_voip.enable = true to false in build.prop
