Audio 'crackle' on WP8 device

Unity Engine
,
1

I’ve got a project that runs fine on iOS and Android, but for some reason is giving an annoying crackle every now and then when playing audio. Tested on Nokia Lumia 630 with Windows Phone 8.1 Update and Nokia Lumia 520 with Windows 8.0.

Is this a known issue? Seems like some of the games in the Unity showcase for WP8 exhibit similar problems (eg Company of Tanks, Pako)

I’ve tried building with v4.6.3 as well as v5.1.0, I’m using the Master version (rather than Debug or Release), have tried switching music to Streaming as well as different compression types and quality rates and also tried changing the DSP Buffer size in Audio Settings, all without success.

Any help fixing this is much appreciated!

Are you profiling your memory and cpu usage on the device?

If either of those are near there limits, it can cause this issue.
