@vi_
thanks for your suggestions, tomorrow i will try.
My situation is kp49 + dsp libs for 720p and camera-ui hd enabled (using kernel default profile).
No other patches or mods.
I installed dsp libs and camera-ui after the first issues with the DSP FAULTS but nothing has changed.

NOW...
Since about 7 hours i disabled VDD1 setting it to zero into the default profile.
Until now ...no battery drain, media player working and no dsp errors!!!

It would be great if someone with the same problem could apply that change to confirm or not if it is a solution....
