Reporting for Lenovo IdeaPad Yoga 13. Inverted channel is visible when
recording stereo in audacity. Mono recording via pulseaudio gives
silence with occasional cracks somewhat corresponding to the sound level
around. Skype and pavucontrol level gauges are also affected.

Changes in balance in pavucontrol do not help with mono recording, I
don't know why.

I'm attaching two patches against oem-audio-hda-daily-
dkms-0.201310111402~ubuntu13.10.1 (https://launchpad.net/~ubuntu-audio-
dev/+archive/alsa-daily); either of them fixes the problem for me (the
-alt one may affect other hardware, though). No additional steps were
needed after applying a patch, building and installing the package.

Output of alsa-info.sh is also attached.
