Check your audio settings by clicking the gear icon in the bottom left of the Discord window. Ensure Input Device is set correctly, and that the Input Volume is up. Also, try disabling and re-enabling the device to refresh the connection.

If you’ve checked your audio settings and still can’t hear anyone, there may be an issue with your network connection. Try closing and re-opening Discord, or restart your router and modem. If the problem persists, check your internet connection and ensure you have a stable connection.
