Why does VoiceMeeter show no sound after install?

Bus A1 has no real output device assigned, or an exclusive-mode app holds the device. Set A1 in the VoiceMeeter menu to your speakers or headset, then System Tray and Restart Audio Engine.

Do I have to reboot after installing VoiceMeeter?

Install it, reboot. The virtual audio drivers register during setup but Windows enumerates them cleanly only after a restart.

The installer asks for administrator rights — is that normal?

Yes. VoiceMeeter installs kernel-mode audio drivers (VAIO), which cannot be registered without elevation.

How to install VoiceMeeter on Windows

Five steps, about ten minutes, one reboot. Applies to Standard, Banana and Potato on Windows 10 and Windows 11; the only difference is which installer build you run and how many outputs you configure afterwards.

DOWNLOAD THE INSTALLER

Step by step

Download. Save VoicemeeterSetup_v2310.zip from the download page. Check the size reads 84 MB before you run anything.
Unzip. Right-click the archive → Extract All. Windows Explorer handles the zip natively; no archiver needed.
Run as administrator. Right-click the installer executable → Run as administrator. Elevation is mandatory: the VAIO virtual audio devices are kernel-mode drivers.
Follow the installer, then reboot. Windows enumerates the new audio endpoints cleanly only after a restart. Skipping the reboot is the single most common cause of “the device is there but silent”.
Assign A1 (and A2). Open VoiceMeeter → menu → System Settings / Options → set A1 to your real speakers or headset. On Banana and Potato set A2 and A3 if you use them. No A1 means no output, no matter what Windows thinks.
Confirm Windows routing. Settings → System → Sound: playback default should be VoiceMeeter Input; recording should list VoiceMeeter Output. Then restart the audio engine from the VoiceMeeter system tray menu.

Route an application through the mixer

Everything through the mixer: leave Windows default playback on VoiceMeeter Input. All system audio lands on the virtual VAIO strip, and you decide which bus it leaves on.
One app through the mixer: Windows Settings → Sound → Volume mixer → per-app output → VoiceMeeter Input. Other apps keep the direct device.
Microphone: pick the hardware input strip (WDM or KS) for the mic, then send that strip to A1 so you hear yourself and to your stream or call app.
Streaming: OBS audio input capture = VoiceMeeter Output; OBS desktop audio = VoiceMeeter Input.

When it goes wrong

Symptom	Cause	Fix
Silent output, meters still move	No A1 device assigned	VoiceMeeter menu → System Settings → A1 = real speaker/headset
Meters dead, Windows plays fine	Windows default playback is still the hardware device	Set default playback to VoiceMeeter Input
Device missing after install	Reboot skipped or driver install blocked	Reboot; if still missing, reinstall as administrator and check Device Manager
Crackling or dropouts	Buffer too small, or ASIO exclusive mode in another app	Raise the buffer to 512/1024 samples; close or reconfigure the exclusive-mode app
Mic not heard in a call	Call app input set to the hardware mic, not the mixer	Set the call app microphone to VoiceMeeter Output
Echo in Discord/OBS	Mic strip routed back into the same bus you monitor	Unroute the mic from A1 and keep it on the virtual bus only

Uninstall cleanly

Run the VoiceMeeter uninstaller from Settings → Apps.
Reboot.
Device Manager → Sound, video and game controllers → remove leftover VAIO devices if any remain.
Reboot again. Windows rebuilds the endpoint list without the virtual devices.
