First, let me complement the developers of this wonderful rom. I have been immensely impressed by all involved. I would urge all who keep using this rom to donate to these hard working and incredibly dedicated developers.Since I feel I put the idea of using beats into the minds of the developers I decided to install this update today to to see if I could help all of you having sound problems; and the solution is simple.
.
So here is what I did. I dirty wiped 2.9 as someone recommended - just factory reset cache dalvik system- installed 3 and set it up. Got rid of Apollo. It doesn't work with awesome beats v3. Flashed the awesome beats v3 zip but left the DSP manager in the rom .Usually I remove it because v3 is it's own DSP manager. Didn't touch sound effects. Awesome beats v3 integrated with DSP manager and improves it's sound so I set up the manager the way I like it and It works fine. Simple solution. But in many cases a DSP manager in a rom will interfere with v3 and needs to be removed but not here . It's one less thing to do.
