Are you using LW's internal player to play songs? It's not a good player & things can sound especially bad if you're trying to play songs & have files uploading/downloading at the same time Try disabling LW's player & using another player.

Likewise for your email videos - have you tried using a different player? If so, which players have you tried? VLC is a good free one to try, there's a download link within this thread: http://www.gnutellaforums.com/tips-t...p3-fixers.html

Otherwise, have you checked out your computer's audio settings via Control Panel > Audio Devices?
