Do NOT report bugs you experience while using this build. It's unofficial, and the patches in it could very well be the cause. This in regard to the 'burst into static thing'.
Our rules are very strict: If you're reporting a bug, be using an official build of Rockbox and an official bootloader, and be able to reproduce the bug.
If you're using an unofficial bootloader or build, it could be any of the modifications that are causing the bug. Even if it seems unlikely, there have been some very strange side effects to some patches.
