Fix sound and microphone problems

I cannot hear the teacher

• On iPhone, look for a "Tap to enable sound" prompt at the top of the screen — iOS blocks audio until you tap once. Tapping anywhere unlocks it.
• Check your ringer/silent switch and volume.
• If it stays silent, leave the lesson and start a fresh session — a stale connection can eat the audio.

The teacher cannot hear me

• Make sure you allowed microphone access when the browser asked. If you declined, re-enable it in the address-bar site settings and reload.
• Check you are not muted — the microphone button at the bottom of the live room toggles mute and turns red when muted.
• On laptops with external audio gear, confirm the browser is using the microphone you expect.

Echo, or the teacher answers itself

If your teacher seems to respond to its own voice, your speakers are feeding back into your microphone. Headphones fix this completely, and are the single best upgrade to lesson quality on any device.
