Hi!!
Since The Phoenix Lander is kinda of Spin-off project of the (in)famous Mars Polar Lander; Phoenix has a microphone like it's predecessor there on mars.
But (I think) due to budget limits (or other thinks like this) it has been turned off also because there's NO SOFTWARE to manage it.
I wonder also WHY ON MARS NASA NEVER used a CHEAP THINK like a trivial webcam.
I said LIKE: I know that on mars poles thmperatures are way far from the one here on earth!
Also I agree it would quickly overload the memory, but I think even a low resolution device would have helped ALOT engineers to investigate the mars soil strange behaviour...
Anyone agree?
