Native Instruments Komplete Audio 2 Driver [UPDATED]

Here’s a helpful, concise reference paper for the Native Instruments Komplete Audio 2 driver—covering installation, troubleshooting, and key technical details.

6. Troubleshooting Common Driver Issues

If you are experiencing pops, clicks, or the device is not recognized, try these fixes:

"No Device Found" Error:

  • Swap USB Ports: Try a different USB port. USB 3.0 ports (blue) are preferred, but sometimes USB 2.0 (black) is more stable for audio drivers.
  • Power: If you are using a laptop, ensure it is plugged into power. USB audio interfaces draw significant power.
  • Cable: Replace the USB cable. The Komplete Audio 2 uses a USB-C cable, but it is a standard USB 2.0 data connection.

Crackling / Audio Dropouts:

  • Increase Buffer Size: Open the Control Panel and increase the buffer size (e.g., from 128 to 256).
  • Exclusive Mode (Windows): Go to Windows Sound Control Panel > Playback Devices > Right-click Komplete Audio 2 > Properties > Advanced > Uncheck "Allow applications to take exclusive control of this device."

Firmware Updates:

  • Sometimes the hardware itself needs an update, not just the driver. If you install the driver and the Control Panel prompts you to "Update Firmware," follow those instructions immediately. Do not unplug the device during a firmware update.

Common Driver Symptoms (And How to Fix Them)

You might be searching for this article because you are experiencing one of these:

  • The "No Sound" after Windows Update: Windows sometimes sneaks in a generic USB driver that overwrites the NI specific one.
  • Crackling/Pops: Your buffer size is set too low, or your driver is fighting with another audio device.
  • Device not showing up in Komplete Kontrol: The driver isn't routing the audio correctly to the standalone app.

A Note on Windows 11

The Komplete Audio 2 works beautifully on Windows 11, but only if you disable USB Selective Suspend. Windows likes to cut power to USB ports to save energy. When it does this to your interface, the driver crashes silently. native instruments komplete audio 2 driver

  • Go to Control Panel > Power Options > Change Plan Settings > Change Advanced Power Settings.
  • Find USB Settings > USB Selective Suspend.
  • Set it to Disabled.

Q: Can I use the Komplete Audio 2 driver with other NI hardware (Audio 6, Audio 10)?

A: No. Each NI interface has a dedicated driver. Do not cross-install.

For All Users:

  • Direct USB Port: Do not plug the Komplete Audio 2 into a keyboard’s USB port or a cheap USB hub. Use a direct port on the motherboard.
  • Ground Loop Hum: If you hear a hum, the driver is not the issue. It is a grounding problem. Use a USB isolator ($30 on Amazon) or plug your laptop and interface into the same power strip.
  • Keep Native Access Open: Native Access runs background agents that ensure your driver stays in sync with your DAW. Do not disable it from startup.

Key Capabilities and Requirements

  • Low-latency ASIO support on Windows for DAWs.
  • Sample rates typically supported up to 192 kHz (confirm with current firmware/spec sheet).
  • USB 2.0 bus-powered operation; stable USB connection required.
  • Compatible with major DAWs; buffer size and sample rate adjustable in both OS and DAW.

9. Quick Diagnostic Checklist

  • [ ] Driver installed? (Windows: see Device Manager → Sound controllers)
  • [ ] USB cable working? (test with another device)
  • [ ] Sample rate matched between DAW and Windows sound settings?
  • [ ] No other app locking the driver (e.g., YouTube, Spotify)?
  • [ ] Mix knob not fully clockwise? (that’s full playback, no input)
