Sound not working / no audio on iOS app (iPhone, iPad)

Looks like a great app. I’m just having issues listening to the videos. There seems to be no sound.

I’m on an iPhone 6 plus
Have you had any issues with this?

This was sent to us via email and we think the answer is something other users may be interested in

Every user that has reported this issue has had the master hardware volume switch on the side of the iPhone/iPad set to “off”. Can you double check to make sure that this is on when using the Hooktheory app (see image below) ?

We realize many video and music apps (iTunes, YouTube, Netflix, etc.) don’t mute their output based on the status of that switch. We are working on a fix so the audio from our app plays even when the master hardware with is set to off.

On newer iOS devices, the hardware switch has been removed and replaced by a software setting accessible by swiping up

There is a setting in Settings/Sounds which silences the typing and the lock sound. It is not that.

There is a bell symbol in the software switches (NOT at the top as an indicator icon to show an existing status) you can find by swiping up. It you tap it once it toggles on and off. This can cause a muting of the sound with Hooktheory I and Hooktheory II book/apps.

Thanks. That fixed it. :slight_smile:

Last time my iPhone don’t produce sound when I receive calls, I have tried all the fixes that I can find.
Then I found Joyoshare iPhone System Recovery and I tried it with suspicion. To my surprise, it actually works and got my ringing back. So if you guys have any sound problem on your iPhone, you might want to try this software.

You should turn up the volume. Press ‘Setting’> Find ‘Sound Haptics’ > Drag the soundbar to the right.
If you still can’t fix your problem, you can try to restore your phone to factory settings.
Or you can also use some iOS system recovery software named TunesKit to fix this problem.
