Gv Audio Driver May 2026

Microsoft has a habit of overwriting custom audio drivers with generic "High Definition Audio Device" drivers.

GV typically refers to Genesys Logic, a Taiwanese semiconductor company known for USB hub controllers, card readers, and USB audio bridge chips (e.g., GL322x series for audio + video capture). A GV Audio Driver is the software interface that enables your operating system to communicate with Genesys Logic’s audio processing hardware, often embedded in:

Common chip families: GL3224, GL3225, GL3520 (audio subset), GL860A (older). gv audio driver

The driver is not universal; it is tied to specific product families. If you are searching for "gv audio driver," you likely own one of the following:

Note: For modern USB-based devices (like the GV USB Mobile), a separate "GV USB Audio Driver" is sometimes required, but the core logic remains identical. Microsoft has a habit of overwriting custom audio

If you are using a GV audio driver for live streaming (not just security), you need sub-10ms latency. Out of the box, these drivers prioritize stability over speed.

Q: Do I need the GV audio driver if I only record video? A: No. The audio driver is strictly for audio capture. If you do not connect microphones, do not install it—it only adds another potential point of failure. GV typically refers to Genesys Logic , a

Q: Why does my GV audio driver show up as "GV A/V Capture" instead of "Audio Device"? A: That indicates you installed a combined video/audio driver package. Right-click it → Properties → Details → check Hardware Ids. If it contains VEN_141F (GeoVision's vendor ID), it is correct.

Q: Can I use the GV audio driver with OBS Studio? A: Yes. Add a new Audio Input Capture source. Select GV Audio (WDM) from the device list. If it doesn't appear, run OBS as administrator.

Q: My GV audio driver works, but the level is too quiet. A: Open the GV Audio Control Panel. Increase the Input Gain from 0dB to +12dB. Be careful—analog noise floor rises with gain.
