I'm confirming this bug because I have noticed that I cannot get sound on a fresh installation on Lenovo Y410. However, with the following modprobe option, I can get sound, but without headphone jack support.
option snd-hda-intel model=fujitsu
The problem here (I believe) is that the snd-hda-intel driver in ALSA Drivers 1.0.16, which is included in Ubuntu Hardy's kernels by default lacks support for the specific variant of Realtek ALC262 used by Lenovo 3000 Y410. Hence, auto-detection of the codec fails and sound doesn't work by default.

Support for Lenovo Y410 had been added in ALSA Drivers 1.0.17, and I have tested it using this script: http:// ubuntuforums. org/showthread. php?t=820959
