I use waveout, sound card is SB Live Value, the OS is Windows 98se, Directx 8.0a, random skin is off, never had random skin on...
I did not have this lag in Starcraft long time ago(around April 2000) if I remembered correctly, I think around Oct. 2000 til now lag started, so I stopped using winamp when playing Starcraft, not sure what caused it... As soon as I noticed there was lag, I started trying out different versions of winamp, but that didn't fix the problem... Since I don't use winamp much before, I couldn't have known what caused this lag..., but could be that my system is getting old and bloated softwares these days... I am glad that Winamp is still nice n small as always.
But anyhow, I'm upgrading my comp. soon, I'll let you know if this problem still exists afterwards...
Thanks for your help!
