I have my Evo paired with my Sony car audio system via bluetooth and now my ringer no longer works. I have disabled bluetooth on the phone and still no luck. My sound profile is set to normal. I can listen to media such as Pandora and Slacker only when I use a headset. I tried a hard reset and everthing worked fine, but as soon as I pair the Evo to my car bluetooth, I experience the same problem again. Anyone else experienced this?
