I also have a very noticeable hissing issue and the weird thing is I don’t think it was there before! Only after I had to struggle to get the card to work after it stopped working when I updated the BIOS it appeared. This is starting to be very annoying. I have the latest firmware installed.
Steinberg told me reinstalling the firmware will damage the card and I am not sure if I reinstalled the firmware update when I was trying to get this thing to work and now I am paranoid if I broke my MR. Although I cannot see how the reinstallation would cause the hissing problem to appear.
Is there a possibility the card is somehow damaged? Is a hiss a typical symptom of a faulty soundcard?
Ps. The headphones do not hiss almost at all. Only a very slight hiss when you boost up the volume all the way up.
