[PD] udoo board sound issues

[David Medine]

BTW, not to overstate the obvious, but...

A good way to measure total latency is with an oscilloscope. Hook up one 
probe to the mic, the other probe to a wire coming out of an output on 
your device. Then make a patch that sends the sound straight through, eg:

[adc~]

If you stimulate the mic with an impulse of some sort, you should see a 
spike and then the same spike a few (or perhaps more than a few) ms 
later on the scope. You can be very exact about this by using the scope 
correctly.

For a bonus, subtract the latency on Pd (one of the settings in audio 
settings) from this to find out the latency of everything in your signal 
chain that is not due to Pd.
