This is the most important section for any user. The software philosophy for the MVSILICON B1 is fundamentally different from that of premium brands like Focusrite or Audio-Technica.
Standard 48,000 Hz (48kHz) recording and playback.
If you experience dropouts while using the USB audio interface, check your operating system's audio sample rate settings. Aligning the OS sample rate (e.g., 48kHz) with the B1 chip’s native firmware sample rate usually resolves sync issues.
The MVSilicon B1 chip family is a highly integrated, low-power audio processor widely used in Bluetooth speakers, soundbars, PC USB microphones, and external sound cards. To unlock its full hardware potential, you must use the proprietary MVSilicon B1 USB audio software suite. This software allows developers and audio engineers to configure USB audio descriptors, tune Digital Signal Processing (DSP) parameters, and flash custom firmware. mvsilicon b1 usb audio software
Are you looking to these drivers for a specific device, or are you developing a product using MVSilicon chips?
The most common filename for this software is CM108_Setup.exe , CM119_Setup.exe , or USB_Audio_Control_Panel.exe . These reference C-Media chips, which are functionally identical to MVSilicon B1 in most consumer products.

Recognized as "mvsilicon B1 usb audio" in System Sound settings. Drivers (like version 4.2.8) are available for legacy support on Windows XP through Windows 10/11.
While the B1 is a legacy chipset, it remains in production because its price-to-performance ratio is nearly impossible to beat for simple USB audio applications. Thousands of OEM manufacturers continue to rely on it for their consumer audio products.
The MVSilicon B1 is a highly integrated, low-power USB audio system-on-chip (SoC) widely used in PC gaming headsets, external sound cards, studio microphones, and audio adapters. To unlock the full potential of this hardware, configuring the and tools is essential. If you experience dropouts while using the USB
In the Advanced tab, you may see:
Setting up the USB Audio interface correctly ensures the B1 chip communicates seamlessly with Windows, macOS, Android, and iOS devices without requiring third-party drivers.
EFUSE configuration for security and MAC address assignments. 2. Configuring USB Audio Descriptors
No third-party driver download is strictly required for basic functionality. The operating system automatically loads its native USB audio driver upon connection.
