In the Advanced tab, you will see two checkboxes under the Exclusive Mode section:
Below these options, you will also see a Default Format dropdown menu. This setting applies only to shared mode and does not affect WASAPI Exclusive playback. In exclusive mode, the audio format is determined by your playback software, not this dropdown.
Exclusive Mode is a protocol within operating systems (Windows WASAPI, Apple Core Audio, and Linux ALSA) that allows an audio application—like a music player or DAW—to take sole control of the USB audio device.
Both boxes should be . The first checkbox permits software to request exclusive access, while the second ensures that when an application requests exclusive mode, it receives priority over other applications attempting to share the device.
The B1 features a range of inputs and outputs, including XLR/TRS combo jacks, MIDI in and out, and a headphone output. It also comes with a comprehensive software suite, including a DAW (digital audio workstation) and a range of plugins and effects. mvsilicon b1 usb audio software exclusive
Recognized automatically by Windows (as "mvsilicon B1 usb audio") without the need for manual driver installation.
Older drivers for the MVSILICON B1, designed for Windows 8, 7, Vista, and XP, are available from third-party driver repositories, though users on Windows 10 and Windows 11 will generally find that the native inbox driver works without issue.
: The Core Audio framework that underpins macOS handles sample rate switching automatically for many applications. For bit-perfect playback, applications like Audirvāna or Roon can take direct control of the output device. No additional configuration of the MVSILICON B1 in System Preferences is typically required, though you may wish to disable system sound effects to avoid interruption.
If you want to dive deeper into configuring this platform, please let me know: In the Advanced tab, you will see two

By default, Windows plays audio through the "Shared" mode. This means the operating system takes all your audio sources (Spotify, YouTube, system sounds), mixes them together, and converts them to a standard format (usually 16-bit/48kHz). While convenient, this adds a layer of software processing that can degrade audio fidelity. Exclusive Mode is a protocol within operating systems
