Thanks for this! I tested these patches plus the ones in your branch
to integrate with the ODROID.
I tested ODROID-U2's 3.5mm analog headphone jack output with:

# speaker-test -c 2 -t wav -l 2

On my x86 laptop this command takes ~6 seconds and produces audible output:
"Front left, front right, front left, front right"

When those words are reproduced over the speakers, there is a
corresponding message printed to stdout which synchronizes nicely.

On ODROID-U2 the same command doesn't work quite right - execution
takes only 3.5 seconds and the audible output is truncated:
"Front left, front right, front"
and the stdout messages do not really coincide with the audio being
reproduced at that time.

No pulseaudio or anything like that.

Can you reproduce this?

Thanks
Daniel
