There are a few older posts about this, but I haven't found a resolution, so I'm reposting. I have my A40s connected to the MixAmp and the Mixamp connected to USB for mic (using optical for audio so that's not an issue). Randomly, my mic will stop working and I cannot hear other people in voice chat (in game or Discord) so there is something going on with the "communication" part of it. I have uninstalled and reinstalled the driver. I have uninstalled and reinstalled Command Center. CC says my firmware is up to date. I have also tried turning off exclusive control and My Windows 10 privacy settings allow for mic usage. The only fix I have found so far is to switch the Mixamp to Console mode and then back to PC. I have to do this multiple times a gaming session.
