That AudioTrack.cpp is from android's framework, not our MediaTrack module, ni Randy for the correct contact window (or please feel free to transfer to the right person, thanks).

libdmd.so is the 3rd frame, which looks a little suspicious.  The gonk code here is the same as v2.0/v2.1 where we have yet to see this particular crash.

Hi Michael, 
Any ideas for that?

Actually what's even more suspicious is that mediaserver is crashing too, right before the snippet from comment 6.  Hmmm....looking at our crash database I see that is common to all 11 instances of this crash to date.

Haven't seen in a while, so closing for now.
