It's a current limitation of the emulator's kernel driver that it only supports 8kHz mono audio for recording. Recent changes to the platform image (in Android 1.5) modify the Audio daemon to want 16kHz by default, and hence broke audio recording in the emulator.
The fix is not trivial unfortunately, because the driver's architecture does not allow for the emulator to detect whether it should emulate an 8kHz or 16kHz recording mike (and we want to keep a single emulator binary to support all existing platforms, so breaking 1.0/1.1 for the benefit of 1.5 is not an option currently). A correct fix would be to extend the driver to let the emulated hardware what sampling rate it needs, and adapt to it (something the emulator can trivially do). This hasn't been fixed yet due to other priorities.
