Below is a patch that fixes the issue for my particular hardware. Pre patch alsa-info: http://www.alsa-project.org/db/?f=a922c77ddf473a8f478ec334fa9dca684f213b59 Post patch alsa-info: http://www.alsa-project.org/db/?f=14cd25b323d3bbb02fabbac78e62851569893c3f Incase you care. The patch is small. I don't know if you need any kind of signed off/written by etc for something so small. In any case there is no intellectual property in this at all. Feel free to do as you wish with it. However including it in the kernel would make my life easier. Thanks, -- Nathanael d.
