Hello, I recently build a dedicated audio PC a two channel using an old Creative labs Audigy 2 ZS and everything works OK except that I have a ultrasonic noise in the audio output. I know is in the audio output because my Amp have power output meters and I can see the meters moving up when there is no sound playback and I turn up the volume. I already change boards and try everything I know but with no results. Any help appreciated.
Thanks and sorry for my English
Eddie
