WO Mic Virtual Device Driver for Windows 10 & 11 (Install & Fix Errors)

The WO Mic Virtual Device driver is the kernel-mode WDM audio driver that makes your smartphone appear in Windows as a standard recording endpoint (Microphone (WO Mic Device)). Without this driver, the PC client can receive audio packets from your phone, but applications like Discord, Zoom, and OBS Studio will not see a microphone.
