Thanks Broni.
I have already downloaded that version of Sound Maker 5.1 but it worked not completely !!The device manager shows no error as it listed the sound device in the installed hardware, but I cant hear any voice from speaker still and the volume systray icon is red-crossed!!
more interesting is that when I run my TV card interface (WINDVR), it plays the sound but when I play a music with win media player or jetaudio,I don't hear anything!!
I am completely mixed up!!
If it isn't still installed why I hear the TV card Sound?
If it is installed then why I cant play music and systray Icon is red-crossed?
thanks for your kind help
