Hi!

Sorry to hear about your problem.

What happens when you attempt to raise the volume while trying to listen to music?

What happens when you uninstall the two apps you mentioned above?

Thanks for the information!

I uninstalled the two apps and rebooted the phone but made no difference. I don't know how to raise the volume when listening to music, doesn't seem to be anything in settings nor in the radio app for that.

There should be physical volume buttons on either the left or the right of your phone; try those.

If that doesn't work, launch the Settings app, tap Sound, and then drag the Media volume slider to the right.

Let me know if my explanation was unclear ; I can post pictures to guide you.

I hope that gets your sound back!

Thats got my radio back thanks. Need to try again with recorder later. peppercat said

When I first got my firefox os phone the radio worked great but since installing a couple of apps (Recorder and Piano) I can no longer get any sound out of radio or either of the apps, nor my videos, either via speaker or headphone although both speaker and headphones work fine for voice calls still.
