So I've had this problem ever since I flashed the CM 11 ROM, and its persisted even after flashing later builds.
To best understand this problem, go to Youtube: Type Atrix 2 Audio issue, and check out the first video. (Sorry! being a noob i'm not allowed to post links yet)
Issue: During outgoing calls to certain cell phone numbers, the caller gets a robotic sound of what the other person is saying. Receiver cant hear anything at all.
Also when receiving calls from certain cell phone numbers(Usually the same numbers with the outgoing problem) the above issue takes place.
I tried the In-call Call Volume app as well, it doesn't fix the issue. Also someone mentioned about switching to 2G, that didnt fix my issue either.
Any help and suggestions would be much appreciated.
Thank you !
