I wonder if MS changed the audio setup in 10 enough to cause issues.
Vista was a big change that caused some interesting driver requirements.
Can you explain the sound difference?
Unfortunately or fortunately depending on how you look at it, I listen to music with a plugin that bypasses the Windows mixer(Using hardware OpenAL[works on some old hardware based creative cards]) and talks directly to my sound card(X-fi). This means Windows has no effect on that part of my sound.
