Extraneous sound in the system


Faced the problem of extraneous sound in the system.

My system configuration:

  • Intel NUC Original BOXNUC8i7BEH2 + SSD INTEL 760p Series SSDPEKKW128G8XT 128Gb, M.2 + CORSAIR Vengeance CMSX16GX4M2A2400C16 DDR4 — 2x 8Gb 2400, SO-DIMM + SSD SAMSUNG 860 Pro MZ-76P2T0BW 2TB, 2.5", SATA III for music. Installed Rock OS.
  • DAC Prima Luna EVO 100
  • Integrated Amplifier Marantz PM10
  • B&W 703
  • Cable AudioQuest Diamond USB A-B
  • Cable AudioQuest Water RCA

Description of the problem: when the computer is connected to the DAC, extraneous sound from the speakers appears. The sound resembles the work of the operating system (squeaking and crackling). This sound is heard at a volume higher than average if you put the song on pause, and also heard in the song, when there are quiet moments in it.

Tell me how to deal with this problem?

Does it happen if you use another music app or just roon?

Music on the hard drive. And then when absolutely without music either.

Hi @Oleg_Sukonny,

Welcome to the forum.
Do you have another USB cable that you can temporarily try using?
What happens if you connect the USB to another of the ROCK ports?
Is the NUC and Amp plugged into an outlet with a surge protector?

Second AudioQuest Forest USB A-B cable. There is also an untitled cable. The problem is not solved.

Connected to all USB ports. The problem is not solved.

Connected surge protector AudioQuest PowerQuest 2. The problem is not solved.

Hello @Oleg_Sukonny,

Do you by any chance have another PC around the house which you can try installing Roon on? I am curious to know if the issue only occurs with the current NUC core. To switch Cores:

  • Open Roon on the other PC you wish to try as the Core
  • Roon Settings -> General
  • Disconnect
  • On the “Choose your Core” screen, press “Use this PC”
  • If asked to Unauthorize, you can go ahead and do so. You are limited to one active Roon Core at a time but you are free to switch between them as often as you’d like.
  • Verify if the same behavior occurs on the different PC

I have a Sony Vaio laptop (windows 7). The Roon program has been installed, but it does not start.

I connected the laptop to the DAC without a program. And again I hear these sounds. And even louder. What does it mean? As if some kind of interference from the computer.

Hi @Oleg_Sukonny,

Do you see any error messages when trying to start Roon on the laptop?

Just to clarify here, you unplugged the DAC from the ROCK which it was previously connected to and plugged it into the Windows 7 PC and the sound is still audible?

That would then suggest that something after the Core is causing the noise - the DAC, Amp, power location that the DAC/Amp is plugged in.

Does the issue happen with just the Amp + speakers plugged in, with no DAC or inputs connected on the Amp?

Roon program terminated. A problem has occured that caused the program to stop working. Close this program.


The problem is only when connecting Roon ROСK or laptop.

Hi @Oleg_Sukonny,

For the Windows 7 install, you may want to try setting up a new database there:

  • Make a Backup of your current Roon Database
  • Exit out of Roon
  • Navigate to your Roon’s Database Location (on the Win7 PC)
  • Find the folder that says “Roon”
  • Rename the “Roon” folder to “Roon_old”
  • Restart/Reinstall the Roon App to generate a new Roon folder

This sounds like it could be due to one of the devices in your chain, have you tried removing or temporarily replacing either the DAC or PreAmp with another one as a test? Do you have any other ones around the house you can give this a try with?

I tested three DACs: Cambridge Audio CXA-61, Exposure XM5 and AUDIO RESEARCH DAC-9. There are no extraneous sounds when connecting Cambridge Audio and Exposure. AUDIO RESEARCH + Marantz PM10 - there is an extraneous sound. AUDIO RESEARCH + Prima Luna Premium HP - there is an extraneous sound. Prima Luna EVO100 + Prima luna Premium HP - there is an extraneous sound.

Hi @Oleg_Sukonny,

Was your laptop on battery power at the time or plugged in? Noise in the system is often related to grounding issues/EMI noise from PC.

Since the issue occurs without Roon running, we can’t really advise further on the hardware aspect, you should reach out to your Roon dealer if you have one or your local audio store to investigate the grounding issues.
