However, it does not work with the current 4.0 wily kernel unless I patch it with these commits: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit?id=e1e62b98ebddc3234f3259019d3236f66fc667f8 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit?id=f3b703326541d0c1ce85f5e570f6d2b6bd4296ec For unrelated reasons, I decided to try the wily 4.1 kernel found here: https://launchpad.net/~canonical-kernel- team/+archive/ubuntu/ppa/. The microphone doesn't work even though Leann Ogasawara confirmed that the above two patches are included upstream. Note I am running vivid userspace, the 4.1 wily kernel from the ppa, bcmwl-kernel-source from wily (since there is a dkms fix) and linux- firmware from wily.
