Hello there. For a while now I haven't been able to make or answer a phone call without using speakerphone or a bluetooth headset. When I try to call or answer the phone without these peripherals I can hear nothing: no dial tone, no voice, etc. The problems started when I flashed AOKP. I accidentally restored the system backups from Titanium backup which it explicitly says not to do in the installation directions for AOKP. I assume this is what caused the problem. For some reason I cannot play sound through play music or the web on the onboard speakers either. It appears that my phone "thinks" that the headphones are always plugged in. The ringer and notification sounds work. I have tried to flash multiple different ROMs, wiped all the caches multiple times, but no luck. Any ideas?
