Here it is, the DSPManager that was missing to Acer based ROM's.
It's new librairies builded from Code Aurora source with DSP code added. (taked from CyanogenMod git)
Tested with success on LCR-F and AOSP v0.2. (Headset and speaker, bluetooth headset was not tested)
Should work on any other Acer based ROM's.
(Remember to make a NANDROID before trying it)
Updated to version 2 : (Fix bad sound at hight volume)
