I am trying to do some DSP with C.H.I.P. but ALSA API call snd_pcm_readi() gets hanged forever.
Have tried arecord from command line and this always returns an I/O error.
I have freshly flashed headless 4.4 on my board.
Is anyone else having similar problems?
Maybe moving to another API (jack for instance) solve the problem or is it a HW/driver problem?
