Comment 14 for bug 1508826

Same thinkpad here. I figured out in the meantime that the headphones must not be plugged in on boot; otherwise they won't work until the next complete power down. If I boot without headphones, however, it works fine.

If you have Alsa 1.0.29 already, you could try the patches from here https://bugzilla.kernel.org/show_bug.cgi?id=99721 (comment 8/9).
