I am using beta edition of Ubuntu 11.10,with lightdm 0.9.3-0ubuntu8,and unity 4.12.0-0ubuntu2,
There is a new feature in Display Manager(well,I didn't notice it in gdm,but it might have been there as well),That you can mute the sound so that login sound wont play(This option exists in the top of the lightdm login page,when you turn on ubuntu and load it)However,Login sound will still play and sound settings will change regardless of what you choose.
