Confirmed, that fixes sound for the Y710. It sounds beautiful, better than Vista.
Optical drive still a problem. I have found several bug reports that sound a lot like my problem:
BUG#8196
BUG#21860
There are others, but these seem the most relevant. 8196 suggests some workarounds in building a custom kernel to make sure that the ide-generic module gets loaded early, but i am not really sure how to do this. 21860 suggests at the very end that the problem still persists in Hardy but was no problem in Gutsy. It appears that this problem has been fixed several times over the life of Ubuntu and it keeps recurring. Definitely looks like a kernel issue... fixing the DSDT may help, but i think we would also have to look at the SSDT...?
I will try installing Gutsy on a spare partition tonight and see if that makes a difference.
