No sound on iPhone
No sound on iPhone is usually the wrong output device, a muted volume, or audio routed to the wrong speakers/headphones. Work through these, then play the channel test.
Step-by-step fix
-
Open Settings → Sounds & Haptics and select the correct output device (laptop speakers, headphones, HDMI/monitor, etc.).
-
Check the volume isn't muted or at zero — system volume and any app volume.
-
Unplug and replug headphones; if using Bluetooth, reconnect the device.
-
Run the CheckMyMic speaker test — play the left, right and both-channel tones.
-
Still silent? Update the audio driver and restart iPhone.
Frequently asked questions
Why is there no sound on iPhone even though volume is up?
Audio is likely routed to the wrong output. Open Settings → Sounds & Haptics and switch the output device, then run the speaker test.
Only one speaker works — how do I fix the balance on iPhone?
Open the speaker test and play Left then Right. If one side is silent, check the balance/pan setting in Settings → Sounds & Haptics.
Still silent after all of that on iPhone — what now?
Plug in wired headphones and play the CheckMyMic speaker test tones. If the headphones play, the audio path works and the fault is the speakers or their connection. If even headphones are silent, it's iPhone's audio stack — reinstall the audio driver and recheck Settings → Sounds & Haptics. Sound missing in only one app? See our Zoom, Teams, Meet, Discord and Chrome sound guides.
My iPhone is stuck in headphone mode with nothing plugged in — help?
Lint in the connector fools the detection — clean the port gently with a dry toothpick or brush, never metal. Turn Bluetooth off to rule out a paired device grabbing the audio, then restart. If the speaker test tones play only through calls but not media, this stuck routing is almost always the cause.
