OK this quirk works perfectly! (hooray!!!)

Does anyone have additional comments to do before I make a patch ?

Let's ask Clemens - the quirks master - for comments :)

Also are there some special ALSA rules or straight signed-off git-formated patches over the kernel tree are OK ?

That's ok. The patch should apply on top of

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git

though.

Thanks again for your help! I'm really happy to have a working device! :D

Good work! I just really wonder what that updated firmware is all about ...
