Hi, Can anyone help me pls? I have just upgrade my system to Vista, it seem my realtek 6.1 onboard sound is working strangely? Everytime I insert a new DVD into DVDROM, the sound goes off (no sound), I have to either restart the pc or logoff and login again to restore the sound? I thought it could be the directsound driver but having found the driver for the directsound, the problem still exist. Any ideas pls?
