Audio not working in the android emulator (win7)

When starting my emulator from Eclipse or from the command line (Win7x32), I see no emulator window popup and the process hangs.

From the command-line, with -verbose, I see logs until the two lines:

emulator: using 'winaudio' audio input backend
emulator: using 'winaudio' audio output backend

... and then nothing.

When I start from the command line with -verbose and -noaudio options, the emulator starts up.

I can modify the Eclipse avd startup settings to have -noaudio, but I'd like to find a way to get audio working.

The commands emulator -help-audio-in and emulator -help-audio-out show winaudio and winaudio & sdl, available, respectively.

Does anyone have pointers as to how to get audio working with my emulator?

Edit After this开发者_StackOverflow中文版 happened again, I discovered it was a faulty audio driver - basically a Windows audio driver issue. Reinstalling the driver (and removing any usb-attached audio hardware like webcams, etc.) allowed the emulator to start w/o hanging @ winaudio statements.

As above, after this happened again, I discovered it was a faulty audio driver - basically a Windows audio driver issue.
