I CC'd Yinghai, the author of that patch. That commit went in after
2.6.33, so this is probably a regression between .33 and .34. Can
you open a report at https://bugzilla.kernel.org and respond to this
thread with the URL?
Please attach the complete dmesg (with SND_HDA_INTEL=m) to the
bugzilla.
Thanks a lot for your report!
