The problem was that I couldn’t hear any voice mail. Hmm. I try to call, and no cigar. When I got to the car I could use the bluetooth integration, and it worked fine.

So, I did what I normally do, and I setup an appointment at the Stanford shopping mall store. I just got here, and after a lot of testing they realised that some lint fell into the mic line, and the sensor there told the phone “oh, the headset is on, so pump all AV out through that”.

So, if you don’t hear anything out of your phone, and it wasn’t the speaker setting, or audio sources, give this a try: blow into your mic input.
