Hi All,


I=E2=80=99m 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 I=E2=80=99d like to perform loopback test and compare the sent an=
d
received files to verify data fidelity. Also the test to be repeated
for various data rates and data formats.


I=E2=80=99d like to know how to test this loopback scenario and compare the
sent\received files?


I appreciate any help.
