What VB-Cable enables in your live shows
VB-Cable creates a software audio bridge between a Windows application and your browser, with no mixer UI: ideal for direct routing.
Send Spotify, Deezer, or VLC to CABLE Input; Gniark Live reads CABLE Output.
Route a dedicated player to the virtual cable while speaking on another mic (if the browser allows).
One application at a time to the cable, without capturing all of Windows.
VB-Cable is the driver Voicemeeter uses for VAIO virtual inputs/outputs.

Prerequisites
- Windows 7 through 11 (32 or 64 bit, Arm64 on recent builds)
- Administrator rights to install the driver
- Up-to-date Chrome, Firefox, or Edge for Gniark Live

VBCABLE_Setup_x64.exe(or x86) as administrator. - 3Restart Windows after installation (required by VB-Audio).

CABLE Inputunder output andCABLE Outputunder input. - 5Optional: run
VBCABLE_ControlPanel.exe(included) to verify levels on CABLE Input.
Understanding CABLE Input and CABLE Output
Flow is one-way: Application → CABLE Input → (virtual cable) → CABLE Output → Gniark Live. Do not swap the names: Input = Windows playback, Output = Windows recording.
Configure VB-Cable for a live show
Scenario: stream music from an application
- 1In your player (Spotify, VLC, foobar2000…), open audio settings and choose
CABLE Input (VB-Audio Virtual Cable)as the output device. - 2Start playback: the VB-Cable control panel (or Windows meters) should move on CABLE Input.
- 3In Gniark Live, select
CABLE Output (VB-Audio Virtual Cable)as the microphone. - 4Application audio is now streamed to the live.
Monitoring: hear audio locally
To listen to what goes to the live, enable Listen to this device on CABLE Output (Sound Settings → Input → CABLE Output → Properties). Use headphones so your physical mic does not pick up speakers.
By default VB-Cable is stereo 48 kHz on Windows 10/11. If an app forces another format, open advanced properties for CABLE Input/Output to align sample rate and channels.
Select VB-Cable in Gniark Live
- 1First configure your app output to CABLE Input and verify signal.
- 2Open Gniark Live and start streaming.
- 3Allow microphone access, then choose
CABLE Output (VB-Audio Virtual Cable). - 4Validate with a viewer or second browser before going public.
Gniark Live selects only one microphone device. To mix voice and music in the same stream, use Voicemeeter Banana and select Voicemeeter Output in the browser.
