Android Emulator hangs and cannot quit

I have same issue as reported in Android Emulator h开发者_JAVA百科ang up and impossible to quit. But the suggestion to add -noaudio does not work for me.

Cannot kill the emulator through Task manager also, and have to do a hard-reboot.

Noticed that once in a while, after reboot, I am able to kill the emulator normally. But if the PC reboots again, and try to do the same, killing emulator gives the same problem.

If you attach to the hung emulator-arm process with gdb and do a backtrace you will see:

This appears to be a known bug:

To work around this issue, disable audio input in the AVD manager with "Audio recording support" set to "no", which sets "hw.audioInput=no" in the qemu ini file.
