[ubuntu] audio drivers conflict with windows 7 dual boot?

view story

http://ubuntuforums.org – Hey all, I'm pretty new to Ubuntu, and just managed to get it installed in a dual boot setup with Windows 7. My main issue is when I boot into Ubuntu, then back into Windows 7, my sounds go haywire (it sounds like the gain is amped up to ridiculous proportions). Does anyone know of what might cause a conflict like that for my audio device between Ubuntu and W7? This is Ubuntu 11.10 (please let me know if there's any other info I should provide). Thanks in advance! (Hardware)
