That is weird. The mute button is now working perfectly for me in Lucid, since I started beta testing it, and today it is still working (with latest updates applied). Though I had also the problem with Karmic like everyone. I have a Lenovo Thinkpad T500 and I'm using the 32bit version of Ubuntu Desktop.
