Hi All,


Iâm having a sound hardware which contains an analogue audio
CODEC(CS42888) and configuring the CODEC is performed over SPI bus.


I noticed that linux kernel already had a driver(snd-soc-cs42xx8.ko)
for this, I planned to use this driver.


Basically Iâd like to perform loopback test and compare the sent and
received files to verify data fidelity. Also the test to be repeated
for various data rates and data formats.


Iâd like to know how to test this loopback scenario and compare the
sent\received files?


I appreciate any help.
