Well i tried with 3 msi motherboards and the problem is same.
After instalation of windows xp sp1 i instaled sound drivers and they worked fine,but
when i install sp2 or when i install slipstreamd sp2 and only sound drivers there is no sound on green output port.
I tried 5 diferent drivers,million settings everything but i could not resolve problem
Windows detects playing sound in graphic equiliser on media player or winamp but there is no sound on either conector.
Any ideas ....i tried with latest msi and realtek drivers,i flashed bios to last version,i even changed procesor and memory sticks but no results...
