Tried to search through the mailing list on this, but didn’t find any solutions. 

I am using ubuntu ARM with the following kernel: 2.6.35-rc6-dl12 #1 PREEMPT Wed Jul 28 13:11:51 UTC 2010 armv7l GNU/Linux

 

Following messages appear in dmesg:

Following messages appear during aplay test:

This appears to be an issue maybe with the driver that alsa is using for the twl4030?  Has anyone else ran into this issue and care to point me in the right direction?
