V. Instructions for Use
Connecting devices
Please use a cable with at least one Type-C end to connect the decoder and the host device.
The host device can be a player, mobile phone, computer, tablet, or a dedicated digital broadcast device.
Due to differences in player, phone, tablet systems, and hardware, some devices may encounter compatibility issues. Additionally, some phones may require manual activation of the OTG function for normal use.
Windows computers
For detailed instructions, please refer to the "USB DAC User Guide".
For Windows computers, the Windows system does not support the UAC2.0 protocol on versions earlier than Win7/Win8/Win10 1703, so a driver needs to be installed.
As versions of Win7/Win8/Win10 prior to 1703 do not support the UAC2.0 protocol, please refer to this link for driver installation [TBD] to achieve a better experience.
The versions after Win10 1703 come with the driver already installed, so you can directly connect it via USB and start using it. If you encounter any issues, you can refer to this link for solutions.
Drivers can also be installed on Windows 10 versions later than 1703, allowing the use of ASIO drivers for a better experience. For information on driver installation, please refer to [TBD].
Android player, mobile phone, or tablet
Android players, phones, or tablets can be categorized into exclusive and non-exclusive modes. For usage inquiries, please refer to here.
Simply plug the USB decoder into the USB port of your phone and use it.
If there is no response after insertion, you can enter the system settings to check if there is an OTG option to enable OTG support on your phone. Alternatively, you can download Haibei Music and try its exclusive mode. If it still doesn't work, it may be that your phone does not support it. Please contact the phone manufacturer for confirmation.

Linux distributions
Linux's support for USB DACs is determined by the kernel. It is uncertain whether the USB sound card function is enabled in different distributions' kernels. For Linux distributions that do not support USB DACs, users can compile the kernel themselves to enable the USB sound card function. Alternatively, they can seek third-party applications to support the USB DAC function.
