Comment 37 for bug 893402

I am not sure what you call 'Panda validation image'. I know there have been some recent kernel changes around these issues, and that the related patches have not yet reached kernel packages or releases everywhere.

Also, the mixers config are important and are not up to date in all versions yet either. I can certify you that Ubuntu 11.10 install + TI add-ons works for this use-case. It brings both the kernel patches, and the user-space side mixers configs.

Could you try installing this image + upgrade with TI ppa? At least it shall permit to define a reference working setup.
