[iOS] Sound volume of music playing on the device gets quiet after launching a Unity app
When a Unity app is launched, any audio playing on the device (iTunes, Spotify, etc.) gets quiet, even when the app is not playing any sounds. This issue does not occur when 'Disable Unity Audio' is checked in Edit > Project Settings > Audio. When the app goes back to background or is exited, the sound goes back to normal.
Steps to reproduce:
1) Create a new project.
2) Build for iOS.
3) Play music on a device.
4) Launch the build on the device.
As soon as the app starts, the sound volume is halved.
Reproduced on:
5.5.0b2, 5.4.0p4, 5.3.6p4
Did not reproduce:
5.2.4f1

This issue started happening suddenly on my iPhone but not my iPad. Turning off "Prepare IOS for Recording", resolved it. I have no idea when this option was enabled.
THANKS PIXELOMESEP - this worked

This is Dec 1 2017 and this bug is not fixed. Sound is perfect on my computer but when I upload to my iPhone the sound can barely be heard. Funny thing is that before it was almost OK. Without sound it is like watching an action moview without sound. HELP if there is anyone home please try to resolve this issue. I am sure it is an easy fix

It's not solved.
On all versions of unity, after 5.3.4f1.

Chiming in again to say that this issue appears to be fixed in 5.4.3p1 on my end although I didn't see any specific mention of it in the patch notes.
