Hi All,

I’m 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’d 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.

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

I appreciate any help.
