I'm working on a tablet for my partner and I notice all sounds had stopped. As an experiment I plugged in a set of headphones and the speakers started working. It was working fine after I had flashed the Brazil ROM for 2.2.1 and setup root, etc. Not sure when it exactly stopped working correctly. Any ideas for a solution? Edit When I use the volume buttons, it beeps. I'm perplexed. I have another setup nearly the same way with no issues. Edit The microphone no longer works unless the headphones are plugged in as well.
