* commit '5a0a0fbde4e180ebad3917b0a2da9921d85f5b9d':
cts_audio work: initial code - volume calibration and THD test case work tuned. - 59 unit tests pass - local audio playback / recording works : uses tinyalsa - host to device ptorocol in host side implemented / tested (with loopback) - device side recording / playback works for test cases / test_io.xml - python processing baseline added. - spectrum algorithm implementated: calculate Transfer Function of device over host and check if amplitudes are within margain. Needs parameter tuning - spectrum test needs some improvements due to the non-flat response from ref microphone.
