Hello, I bought the Asus Xonar Essence ST PCI sound card after hearing so much good stuff about it.
But I've encountered a problem with the card. When I use my IEM to listen music on my computer, I hear a constant hissing noise. Since the Xonar Essence has such a good signal-to-noise ratio and all the EMI shielding, I'm thinking I shouldn't be hearing this constant background noise. Of course, I'm a noob and do not fully understand what those terms mean, but it sounds like it has to do with noise. I'm seriously considering if this is a product defect and if I should RMA this.
Here are some details so you guys can help me better:
-The noise is present all the time when the IEM is connected to the port. Whether I change the sound output to the RCA outputs or others do not matter. Whenever the computer is on and my IEM is connected to the headphone port, it puts out a constant hissing hum.
-I don't really hear that much of a hum when using other headphones, but I think that's because IEMs get better noise isolation.
-IEM model is Shure SCL-3 if that helps.
Also, I know that there is definately noise coming from my sound card because I don't get that sort of noise when I connect to my mp3 player or any other sound source.
I've been using the card for nearly five months now, and I've been hearing that noise ever since I bought the card. I kind of ignored it until now, but now it's really bugging me. Additionally, I don't think I heard too much of a sound quality improvement from the Xonar Essence over my onboard sound card, maybe I think that because on the other side of my head I think the card is defective. Anyway, I'm wondering if any of you fellow Xonar Essence users experience this and if you guys think I have a defective product and should RMA it.
Thanks a bunch!
