Installed on my Sprint TP2. Hissing/static begins during Android bootup and continues when fully booted. Pressing volume/calling the phone will stop it momentarily but it always begins again. Tried changing startup.txt cpu frequency setting back to 500 (or stock) but that made no difference. Also, when on a call, the speaker phone does not output sound and if you put it in speaker phone mode this will cause the sound to mute on the phone.

Only report this to help those who have come this far diagnose what may be wrong, if they care to do so. I remain appreciative of everyone's efforts!
