If YAPYAP can’t detect your microphone, it’s usually the input device, permissions, or a conflict with other audio apps. Start here.
- Replug the mic / try another USB port
- Confirm Windows Input level moves when you speak
- Set the mic as Default Input Device
- Restart the game after changing inputs
- Select the correct input device in Windows Sound settings
- Allow microphone access in Windows Privacy settings
- Disable Exclusive Mode to avoid app conflicts
Steam → Friends & Chat → ⚙ → Voice
- Select the correct input
- Run Microphone Test
- Confirm transmission type (PTT/Voice activation) and keybinds
Close Discord / OBS / NVIDIA Broadcast / virtual audio tools, then relaunch Steam and test again.
That usually points to voice chat rather than voice casting. Re-check Steam Voice settings and in-game voice toggles.
