I’ve had a Steinberg CI1 USB audio interface for years now, but when I tried it in my newly built desktop computer, the connected speakers started making this hissing noise with beeps. It works fine on my old laptop, and also it works fine just using a headset. The computer build has a topend PSU, so I doubt that it is interference, but nevertheless I will check into that. All drivers are up to date, inputs are working fine (I tried it through cubase), and the hissing is still there even with other speakers and cables. Is there anything else I can check for before buying a new USB audio interface?
