Problem solved. I picked up an isolator and the noise is gone. Dead silent. Thanks for the suggestion!

Reporting back that this was unsuccessful.

Since firing up the new build, I have been experiencing occasional glitches during playback. So, the first thing I did was to download and run LatencyMon. I let it run for a while and it gave me this conclusion: Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates. The first thing I did was to optimize the power settings to High Performance, turned off power throttling in the registry, and disabled C States in the BIOS (which was also updated). Also turned off WiFi and Real Time Scanning. After all that, I'm still getting the same message. Below is the report. _________________________________________________________________________________________________________ CONCLUSION _________________________________________________________________________________________________________ Your system appears to be having trouble handling real-time audio and other tasks.

This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.

Thanks for the info, Jim. I replaced the OEM interface cable with a shorter Anker cable and it's still there. Next will be to get some ferrite beads. I had also disconnected the WiFi antenna from the mobo and it's still there.

I captured the noise, just for reference. New Recording 7.m4a

Both mouse and keyboard are wired. Unplugged them both as a test. Sound is still there. Also, tried a different USB-C cable, tried different speaker cables, tried relocating the interface, and unplugged the WiFi antenna and put the PC in airplane mode. No luck. Also, the sound disappears when the PC is shut down.

Thanks Jim (and others) for the reply. To your points, Jim: Yes, everything is powered by a single outlet. My speakers and monitor are plugged into a Furman conditioner which is plugged in to a UPS. The PC is also plugged into the UPS. All cables are balanced. I'm going to get shorter cables for my HS-50s (which are the only speakers making the noise). Currently 6-foot but can easily use 3-foot. I'm also getting a new, shorter USB-C cable for the interface. I did unplug both pair of speakers from the interface and no noise can be heard through the headphones. So, it appears to be isolated to the HS-50s. Also, I am not using the external power supply on the interface. I'll keep you posted if find the culprit.

Regarding that, none of the cables have moved and this wasn't present with my old PC.

I just got a new interface for my new build and I'm noticing a faint buzz or static coming out of my HS-50's (but strangely, not from my Event TR8's). It gets worse when I move my mouse around. Whether the interface is on or off, it's there. I've isolated it to the USB-C connection. When I unplug the cable, the noise goes away. I've tried 3 different USB-C connections on the computer and even one of the Type A connections with an adapter, with no luck. Also tried unplugging the display power and moving one of the HS-50's away from the computer. Has anyone ever experienced this? Also, you don't hear it through the headphone outputs; only the speakers.

Thanks, guys. I thought the one I was trying was the newest; it was not.

This is my favorite theme. Did you ever update it for 2024.12?

I'm building a new Windows 11 PC and if the Pro 40 is not compatible, then a new USB interface is what I'll have to get.

Good to know. Thanks!

You're not kidding. Hence my question. I'd rather not add 200-300 dollars to my build unless absolutely necessary.

I'm starting a new build and research tell me that I might not be able to use my Focusrite Saffire Pro 40. I've read in various places that firewire may or may not work with Windows 11. Some say it works using legacy drivers, others say it doesn't. Does anyone have any experience with firewire audio interfaces on Windows 11?
