I try to record audio in stereo and it always fails, when I get the
minbuffersize i get the error:
I/ActivityManager( 2147): Start proc com.example.recorder for activity
com.example.recorder/.MainActivity: pid=3478 uid=10035 gids={1015}
E/AudioRecord-Java( 3478): [ android.media.AudioRecord ]
getMinBufferSize(): Invalid audio format.
I/System.out( 3478): Buffer size -2
I/SurfaceFlinger( 2147): mHw->getFormat() 4
and if I force a min buffer size it throws:
W/dalvikvm( 3553): threadid=1: thread exiting with uncaught exception

It's odd cuz alsamixer for SGTL5000 gives me the option of capture
left/right volume levels:
Simple mixer control 'Capture',0
Capabilities: cvolume penum
Capture channels: Front Left - Front Right
Limits: Capture 0 - 15
Front Left: Capture 15 [100%]
Front Right: Capture 15 [100%]
However I cannot test it cuz i don't have alsa_arecord (that's another
problem i'm having).
