Waiting waiting.....Plzzzz fix the dsp manager in v6.5.8...
For dsp manager issue.
Remove it from system/app using whatever.
Download this, https://market.android.com/details?id=com.lukemovement.roottoolbox.free
Open it, grant it superuser, go into others, scroll down till you see install Cyanogen DSP Manager. This version works.
Press thanks if I helped
