Check there is no presence of our virtual audio driver in Windows Device Manager (in both sections: multimedia controller and audio input output).
Check your remaining audio devices are working correctly. De-install VB-CABLE one by one + REBOOT. If nothing helps to get a stable stream, it usually means that one or several audio drivers are not correctly installed.ĭon’t forget to REBOOT after the audio driver installation (or de-installation) – this is also true for any new USB audio device that you plug on your computer – even if installation is automatic, it’s better to reboot after. Then you may increase internal latency with the VBCABLE_ControlPanel app installed with Voicemeeter (there is one ControlPanel for each virtual audio cable – used as virtual audio I/O by Voicemeeter). The default value is 7168 samples, but this may not be enough to ensure a stable stream on a virtual link (depending on the buffer used by the application connected to it – for example, 7168 samples may not be enough if the capture app uses a 4096 sample buffer). You may check the internal latency of the related VAIO (virtual audio I/O). The buffer-related issue can sometimes be found in a virtual audio path, such as from the VOICEMEETER virtual output (BUS B1, B2, or B3) to a capture application (Discord, Skype, etc…). If buffers are to small or have the wrong size to work with a software, which uses a different buffer size, it can result in crackles or dropouts. Smaller buffer sizes result in lower latency (which everyone wants), but also in higher buffer numbers and a higher CPU load. The stream might be unstable and it could be better to use an existing KS or MME driver.Ĭhange the buffers for the Virtual Audio PathĪudio on PCs always works with buffers and buffer sizes, which are processed by the CPU and the overall system. In this case, the device will be used in SHARE mode (a “S” is displayed in System Settings Dialog box – right to the output A1 Device audio format). But the device could refuse in some cases, because it is already in use or because the eclusive mode is disabled. So this device must work correctly.Ī WDM device will be used in EXCLUSIVE mode per default. The output A1 device is used to generate the master audio stream, all other I/O and streams will be based on it. The device selected as output A1 sends the main stream. MME with 512-1024 sample buffer size (as a last choice). an ASIO device if it presented with 256 or 512 sample buffer size. This gives the most stable device for the main audio output. 
Keep your default settings – default buffer size / default engine mode – and select your best audio device as output A1.
