Yes, it seems so. I don't want to get ahead of myself, but two suspend-resume cycles have passed and inputs are at Internal Mic and Mic, as expected.

Thanks for checking. I committed the fix to git tree, also Cc'ed to stable.

I cannot seem to find this patch in the 3.2 stable tree, was it rejected?

What is the git commit id of it in Linus's tree?

Hmm, it does not seem to be in Linus' tree yet. It is in for-linus branch of sound tree under commit 068b9394 though.

Then there is nothing I can do about it at this point in time.

Dear Greg,

it seems the patch has been merged to the Linus' tree:
