What steps will reproduce the problem?
1. Download, install and configure "Walkie Talkie Push to Talk" program:
http://andappstore.com/AndroidApplications/apps/Walkie_Talkie_Push_to_Talk
2. Try to "Hold Down to Record & Send"
3. Observe the program (and the Android in general) lockup with
battery-ejecton the only way to recover.

What is the expected output? What do you see instead?
To record the audio or graciously fail (application crash), but not the
distro lockup.

What version of the product are you using? On what operating system?

Can someone with included "Audio recorder" application test, whether the

I've tried the SoundRecorder inlcuded in Android, and I get the exact same 
issue. I
even tried adding a default ALSA record profile in etc/asound.conf, basically 
just
copying the AndroidRecord_Microphone to AndroidRecord thinking maybe this was 
the
issue, but I still get the obtainBuffer timeouts.
