Okay, I can reproduce that error here. Here's how to fix:
First:
sudo apt-get remove alsa-intel-hda-update-diwic-ideapad-y550-dkms
Then check if there are traces left with
sudo dkms status
If there are still traces (shows up as "alsa-intel-hda-update-diwic-ideapad-y550, 1.0.23: added" ), do:
sudo dkms remove -m alsa-intel-hda-update-diwic-ideapad-y550 -v 1.0.23 --all
Then download and install http://people.canonical.com/~diwic/temp/alsa-intel-hda-diwic-ideapad-y550-dkms_1.0.23.diwic_all.deb Reboot and retry. Sorry for the inconvenience.
