Posting in the help section also - white noise only

Question

Hello - forgive me if this is a double up. I have a raspberry pi B version 2 with the Volumio image that was modified to include the wolfson drivers by folks on that forum. I have only been able to get white noise out of the line out and headphone out. Here is output from dmesg.

I hope someone can help.

Thanks,

George

Volumio 1.4 wolfson image - edited config.txt to kernel=kernel_new.img - changed the mixer setting to software and ran dmesg.

Here is the output:
