Is it a Virus?
NO - Safe
Should be installed from VB-Audio's official setup (VBCABLE_Setup_x64.exe) and show the VB-Audio signature.
Warning
Multiple virtual devices
Several cables may exist (VB-CABLE, VB-CABLE-A) and require proper routing to avoid feedback.
Can I Disable?
YES
Disable or uninstall via VB-Audio Setup, or stop the Driver service in Services.msc and reboot.
What is vb-audio-cable-driver?
vb-audio-cable-driver is a Windows driver that implements one or more virtual audio cables used to route sound between applications. It appears as new playback and recording endpoints in the Windows sound settings, enabling inter-app audio routing without physical hardware.
The driver exposes virtual audio endpoints (cables) that apps can select as outputs/inputs. It operates at the kernel/user boundary, providing sample-rate and buffer management to transfer audio streams between programs.
Quick Fact: VB-Audio Cable is a lightweight, widely-used virtual audio device compatible with WASAPI, ASIO, and DirectSound in Windows.
Types of VB-Audio Cable Components
- Driver Service: Core Windows service that loads the virtual cable driver
- VB-CABLE Virtual Device: The actual playback/recording endpoints representing the cable
- Installer/Setup: VBCABLE_Setup_x64.exe used to install/repair/uninstall
- Routing Layer: Software layer that forwards audio between apps via the cable
- Control Interfaces: Optional UI tools to manage cables or VOIP routing
Is vb-audio-cable-driver Safe?
Yes, vb-audio-cable-driver is safe when obtained from the official VB-Audio website and installed with administrator privileges.
Is vb-audio-cable-driver a Virus or Malware?
The real driver is not a virus. Malicious files may masquerade as VB-Audio. Verify the signature and source.
How to Tell if vb-audio-cable-driver is Legitimate or Malware
- File Location:: Check for vb-audio-cable.sys under C:\Windows\System32\drivers and the installer in C:\Program Files\VB-AUDIO\VB-CABLE.
- Digital Signature:: Right-click vb-audio-cable.sys in Explorer -> Properties -> Digital Signatures; should show provider 'VB-Audio' and valid cert.
- Vendor Trust:: Confirm the binary came from https://www.vb-audio.com and matches the installer hash.
- Resource Usage:: Normal usage is minimal in idle state; high constant CPU with no audio routing is suspicious.
Red Flags: If you find vb-audio-cable.sys in unusual folders, no signature, or if the driver runs without any audio activity, scan with antivirus and verify installer source.
Why Is vb-audio-cable-driver Running on My PC?
The driver runs whenever you have an active audio routing configuration or background audio software using the virtual cables.
Reasons it's running:
- Active Audio Routing: An application is sending audio through VB-CABLE to another app (e.g., DAW to OBS).
- Background Audio Apps: Utilities like screen recorders or mixers use the cable in the background.
- Default Playback/Recording Device: Windows may route system sounds through VB-CABLE if selected as default output/input.
- Installer or Update Actions: After installing or updating VB-CABLE, the driver starts to finalize the setup.
- VoiceMeeter or Similar Tools: If you use VoiceMeeter or other virtual routing tools, they may activate the cable internally.
Can I Disable or Remove vb-audio-cable-driver?
Yes, you can disable or remove it. It’s safe to uninstall if you don’t use virtual cables, or you can disable it to stop routing.
How to Stop vb-audio-cable-driver
- End Applications Using Cable: Close programs that route audio via VB-CABLE (e.g., OBS, DAWs, or chat apps).
- Disable Startup/Service: Open Services.msc, find 'VB-Audio Cable Driver' and stop or disable the service; reboot.
- Uninstall: Run VB-CABLE Setup (VBCABLE_Setup_x64.exe) and choose Uninstall.
- Default Audio Devices: Set real playback and recording devices as default in Windows Sound settings.
- Repair/Resinstall if Needed: If you plan to reuse, re-run the installer to repair correctly.
How to Uninstall VB-CABLE
- ✔ Run VBCABLE_Setup_x64.exe and select Uninstall
- ✔ Reboot the PC after uninstall
- ✔ Optionally remove remaining VB-AUDIO folder in C:\Program Files\VB-AUDIO
Common Problems: Virtual Cable Issues
If vb-audio-cable-driver has issues, check these common scenarios and fixes.
Common Causes & Solutions
- No audio routing after install: Open Windows Sound settings and set VB-CABLE as the Default Output and Default Input as needed, then re-test.
- Mismatch sample rates between apps: Set all apps to the same sample rate (44.1kHz or 48kHz) in their audio settings.
- Latency or buffering delays: Adjust buffer size in the application or use Wasapi exclusive mode; reduce latency via VB-CABLE settings.
- Driver failed to install: Run the installer as Administrator, disable antivirus during install, and ensure Windows driver signing is not blocked.
- Feedback or hum: Ensure no real-time monitoring on both ends; disable monitoring in applications and set proper routing.
- Conflicts with VoiceMeeter: Disable conflicting virtual devices or reinstall both tools ensuring correct cable names are used.
Quick Fixes:
1. Quick Fixes:
2. 1. Open the VB-CABLE Setup and run Install/Repair
3. Set VB-CABLE as default devices in Windows sound settings
4. Match sample rates across apps (44.1kHz or 48kHz)
5. Restart applications or reboot after changes
6. If issues persist, temporarily disable other virtual audio devices
Frequently Asked Questions
