We’re experiencing audio problems on rooted Android devices with custom firmware. I’m running Note 2 with flashed Lollipop and I have confirmed the problem on Galaxy S2 with Lollipop as well.
I’ve tested this on empty scene with 1 audio source and it does not work.
Audio is completely distorted and it plays very slowly. Game is built with Unity 5.2 Pro.
I have the same problem on rooted Note 2 with Android 5.1.1 (custom rom: resurrection remix 5.5.8).
There’s a thread about the general problem here: Android Sound Latency Fix - Community Showcases - Unity Discussions
I don’t know why rooting a device would affect this, though flashing a replacement ROM (with different drivers) could certainly have an impact.
