After hearing all of your responses to the issue of sound not working, I went ahead and installed Safestrap and tried out the following ROMs:Yes, there is no sound on Slot 1 for the rom I installed, after rebooting.
Primary Rom Sound works fine.
Graviton
GPE 4.2.2
Both worked PERFECTLY, and both have sound - even after a reboot. Thanks everyone, especially Hashcode, for breathing life back into the ATT GS4!
