After allowing my 2yr old to randomly bang around on the control panel, I no longer have AOS sounds (i.e. startup, exit, p1 button, etc.). The actual game sounds work fine, just not the AOS sounds. I tried editing the arcadeos.cfg file to make sure sounds=1 (as outlined in the readme file), but when I start up aos, still no sounds. Then I look at the .cfg file and my edit is gone - as if the .cfg is overwritten with "default" settings. Any ideas?? Thanks.
