Does Arch Linux support new Lenovo Thinkpad Intel audio?

I've installed Arch Linux on many Thinkpads.

Got the newest Lenovo T440s laptop.  Entire dmesg is here: http://pastebin.com/mGNMN0mX

Very nice machine.  But can't get audio to work yet.   alsa-utils is installed.

Typing `alsamixer` gets the old error: "cannot open mixer: No such file or directory" - whether I type it as root or regular user.

I've seen this same error posted many times on the bbs here over the last few years, but none of those solutions worked.

$ amixer sset Master unmute
amixer: Mixer attach default error: No such file or directory

$ aplay -l

Hardware is initialized using a generic method

Any other ideas?

Being a pretty popular Lenovo Thinkpad, I'll bet this will come up again.

Thank you.

A quick search would have revealed this.

Edit: Also, please fix your post and use code tags.  You can see how to do this by following the BBCode link below.
