Starting about a week ago, my BBerry World randomly won't ring for calls/SMS/BBerry chat, etc. If I go into my media and try to play a ringtone or sound clip, nothing happens. Pulling the battery works, usually for about half a day, but then the problem starts up again.
I get this as well and it also seems to effect VZ Navigator as it stops giving me voice prompts. Anyone else noticed this?
I have noticed this with Sprint Navigation. You will also notice that no other apps will play audio either (except maybe the browser with youtube videos, maybe it's the browser that causes these issues).
