onboard sound card: 7.1 CH HD Audio with Content Protection (Realtek ALC892 Audio Codec) ASRock Z77 PRO3 on a mainboard
ultimately I sent back the sound card and resorted to an external USB sound card and an additional USB isolator. since noise-free images.
I would recommend this soundcard someone who has a faulty onboard sound card and the sound actually was satisfied. an upgrade it is not, but a very good substitute.
