Ok guys, please uninstall all the packages I got you to install from my PPA. Then enable the ubuntu-audio-dev PPA ppa:ubuntu-audio-dev/ppa and install linux-alsa-driver-modules-2.6.31-19-generic for karmic, and linux-alsa-driver-modules-2.6.32-13-generic for lucid.
Then open /etc/modprobe.d/alsa-base.conf and add the following line:
options snd-hda-intel model=ideapad
Then reboot
Seems someone sent a patch upstrea for the u150 which very likely uses the same chip as the 350, so if that works, then problem solved, and I only need to add a quirk for the 350 for your machines.
