I have a new Flytouch 2, which I am really happy with except.... The only sound coming from speakers and headset is hissing (very low) no matter what the volume is set at. I have tried with and without WiFi, same results. I have build 1107, I had read this may be an issue, but I don't know what it came with so I don't know if I can roll back. Not even sure how to rollback if possible. Thanks for any help,
