Just casting my complaint in as well. New Type 11 v7.1 install.
Getting terrible static, music/movies are basically unplayable. Inserting headphones does shut off the speakers 100%, but get static in the phones same as the speakers. Using mute button (Fn-4) does not actually turn the speakers all the way off.
Unfortunately, I did not try audio in Ubuntu before I wiped it. I may make up an XP load on an external disk this weekend and see if it's hardware or software. I tend to think at least partly hardware--had an incident where the speakers were making a weird howl during POST, only happened once though.
Not to make anyone mad, but the Mini9s feel a bit cheap (power button, trackpad buttons, screen won't tilt far enough back). Would not suprise me that the audio components are not the best. On the other hand, I paid more for my iPod than this laptop, so can't complain too much.
