The base level (lowest) voice pick-up threshold appears to have been set higher since 1.17. It now will either not pick up or chop up low-volume mics (e.g. with noise cancelling / processing etc.) The problem is the same on lowest in-game audio voice activation threshold setting and push-to-talk. Affected players need to shout into microphone, which will output only choppy sound.
Have you changed the base level voice threshold?
I have set severity to major, as those affected will not be able to use voice in game. Especially affects some content creators.
