Please b gentle with me as I don't really understand 2 much on the hardware/software side. My problem is that YouTube & Bebo(like MySpace) don't have any sound. I can play my MediaPlayer without any problems. I haven't checked 2 c what else has no sound, but I'm guessing it's internet programs. I tried to restore 2 an earlier period, when I thought the sound was still working but it hasn't helped at all. I have Windows XP(Home Ed.),Vers 2002, Service Pack 2. I couldn't tell u what sound card I have as I don't know, but if u need the details, just direct me & I'll look them up. Any help would b much appreciated
