A20 Som Analog Output problems

[davehetfield]

Hi all, I'm using a A20 Som module with the mainline kernel 4.4 and have a problem. After starting an audio (headphone) output  e.g. speaker-test -twav -c2 the first second of the stream is missing. Around 5 seconds at the end of the stream you can hear a click.
Anyideas to fix it? Thanks!

When in doubt, always first test with the official Olimage images here:

Also are you using the A20-SOM-EVB with the A20-SOM for initial research and development?
