Confirm Windows detects the intended microphone and allows desktop-app access.
- 02
Align the default communication device with the game's selected input and output.
- 03
Check format and push-to-talk before changing server or network settings.

Use the local HLL settings-folder reset only after recording settings and exhausting safer checks.
