I cannot hear anyone

• You are deafened. Check the Deafen button next to your name.
• The wrong speakers are picked. Check Speakers and Output volume in Setup > Audio. A headset that is plugged in but not chosen as your system sound device is a common cause.
• One person is too quiet. Right-click them and check Volume and User > Mute (how).
• Nobody is in your channel. You hear the people in your own channel. Double-click a channel to join it.
