The patch applied to precise had a problem. The quirk for U300 was applied to the wrong list (cxt5051_fixups instead of cxt5066_fixups, looking at original alsa info attached here it will consider cxt5066_fixups). The upstream patch was ok, just the diff applied to precise had this issue. It's now fixed in precise master-next using correct version from 3.2.32 stable update (bug 1068162).
