For me i cant tell the difference they are basically exactly the same (arch linux and windows xp same laptop) not so sure with ubuntu though as i have it installed on a different computer then my windows
For me the quality in windows is not as good as my soundcard seems to get more boost under linux

Other than the occasionaly weird sound issue I get, I agree that sound is better in Linux than in Windows(XP). Though like others have said, it is probably highly dependant on which soundcard, and settings you have. But for me, the default settings on my system are better in Ubuntu than in Windows. The bass is more intense and pure, and the trebles are crisper.
I've never noticed any difference in any OS on any computer, maybe it's just not so great speakers? Always seems fine for me, I'll take it

For my sound card(intel HDA), Windows.
for me its the same on both win 7 and lynx but the video quality its a bit better on win 7
THIS Soundcard works awesomely on my machine.
That's my review in the comments section.
I've always had much superior sound quality be it for movies/music whatever in Windows.
