i purchased a used hd2 sound card
and when i play music throw optical there is no problems
but when i try to play throw rca i am getting noise from the speakers in 16 bit mode there is alot of nose and very bad sound
and in 24-bit mode almost no noise and very bad sound , in 16 and 24 bit mode the sound is very loud too, when i switch to optical at the same volume i almost cant hear anything
i think it is a technical issue and not a driver problem ...
can it be the opamp problem ? or maybee something else ?
