Product defect: No sounds when plugged in?
I found three relevant threads (noted below) that describe my problem, though none of them actually solved the issue. This is getting beyond annoying and I need assistance. When plugged into my MacBook Pro 13", and sometimes after a long time of not being rebooted, my 3GS Black 32GB *with no software mods* simply stops making the sounds for SMS, email, and the lock 'click'.
Even if I go into the menu settings for sounds and click them they do not play. Example, changing the SMS sound from glass to chime does nothing until rebooted (but won't work regardless if plugged in to computer). The only sound that seems to continue to work is ring for phone calls. I've missed a lot of SMS and/or notifications from apps through push because of this and all I know is my old iPhone (2G) didn't have the issue. I restored today with iTunes and before syncing the phone with my backup I tried to use click sounds whilst it was plugged in and they didn't work. Therefore it's a hardware and/or software issue with this phone. Anyone know or fix or is it time to drag my butt into Apple?
