I just documented and filed this bug:
https://fogbugz.unity3d.com/default.asp?856580_u4c9ta0ke3m8nn08
It appears to affect Unity 5.3.7, Unity 5.4.1, Unity 5.4.2 and Unity 5.4.3.
These two older versions of Unity were tested as UNAFFECTED by the bug: Unity 5.2.2 and Unity 5.3.4.
Use caution because if you put an iOS app out that mutes the customer's iPod music, they tend to get VERY angry and give your app a 1-star rating. People are very passionate about their music, so don't...
Heads-up: critical iOS audio-muffling bug in Unity 5.4.3 (and other versions)
