Look for the active media destination
Open the phone’s media controls while audio is playing and check the named output. It may show earbuds, a car, television, smart speaker or hearing accessory.
Select the phone speaker or disconnect the accessory. Merely closing its app may not release the route.
Turn Bluetooth off temporarily
For an urgent wet-speaker test, temporarily disabling Bluetooth is the fastest way to remove most wireless routes. Also disconnect wired adapters and USB-C headphones.
Reload the player if the browser held the old output path.
Check app and system volume separately
Media, calls and alarms may use different volume controls. Adjust media volume while the test is playing, not before it starts.
A silent browser tab, muted site or focus mode can also be involved.
Retest at a moderate level
Once sound clearly comes from the phone, begin the nBeats tool at a moderate level. Do not compensate for an incorrect output route by pushing every volume control to maximum.
If the built-in speaker remains silent across apps and after restart, the issue needs broader troubleshooting.
Device-specific safety statements are linked to current manufacturer guidance and independent reporting.
