I am working on the libthread_db issue right now. Is proving to be harder
than I would have expected. Anyway, I did determine the problem causing the
warnings:

warning: pointer targets in passing argument 3 of
'snd_pcm_hw_params_set_rate_near' differ in signedness

was due to sample_rate being defined as an int and not an unsigned int.
Changing that cleared that warning.

I will let you know what happens once I get the libthread_db going.
