Voicemeeter generates static or makes a robot sound

Postby Vincent Burel » Sun Jun 04, 2017 6:54 am

In some cases, Voicemeeter can generate static (cut in the sound) or a robot voice (sound is distorded because discontinued).
This can happend in the first minute... or after having worked well during hours.

In most of cases, you may RESTART AUDIO ENGINE (in Voicemeeter Menu) to get correct sound again.
but if the problem appears too much frequently, it can be a problem of configuration and audio device selection / configuration.

General rules:
All audio Apps should be connected to Voicemeeter or should not use same audio output device than Voicemeeter (to avoid audio device conflict). That’s why we also recommend to set Voicemeeter virtual audio I/O as default playback / recording device.

Output A1 device is crucial
Keep default settings (default buffer size / default engine mode) and select your best audio device as output A1 (giving the main stream): ASIO device if present (with 256 or 512 sample buffer size) … WDM or KS (512 sample buffer size) … MME as last choice (512-1024 sample buffer size).

Device selected as Output A1 gives the main stream
The output A1 device is used to generate the master audio stream, all other I/O and streams will be based on it. So this device must work correct. For WDM device, Voicemeeter opens it in EXCLUSIVE mode per default... But the device could refuse in some cases, or because already in use, or because Eclusive mode is disabled. Then this device will be used in SHARE mode (a "S" is diaplayed in System Settings Dialog box - right to the output A1 Device audio format). In this case, the stream might be unstable and it could be better to use KS or MME.

In all cases you must test it on significant duration to validate your configuration before going on air.
If the problem remains, send a screenshot of Voicemeeter and its system settings dialog box to let us see your configuration.

Persistent audio crackling with Voicemeeter, cut or tic in the sound.

if nothing can help to get a stable stream, it usually means that one or several audio drivers are not well installed.
Also don't forget to REBOOT after audio driver installation (or de-installation) - this is also true for USB audio device that you plug on your computer (even if installation is automatic, it's better to reboot after).

Anyway your VB-CABLE or Voicemeeter VAIO's must appear like on the picture below for Playback and Recording Devices. Otherwise you should re-install them correctly.
