Dear respected customers,
All the existing X-Series DAPs (except X1) can work as DAC for the computer. Each time we release a new official firmware on our website and forum, we provide the DAC drivers (v1.61.0) of the players for customers to install it on Windows computer.
However, although there is no need to install the DAC driver for iOS system users, but it is still required to disable the driver signature verification for Windows 8/10 users before the installation, while the majority users are using computers running Window 8/10 nowadays.
Therefore, in order to improve the user experience, we have made a major upgrade to this Windows DAC driver -- from the ancient v1.61.0 to the shiniest latest v3.34.0, which enables you to install the DAC driver directly without make any extra settings.
Thank Thesycon company for working with us to work out the licensing plan for their latest and greatest!
With the brand new UI of the driver, this unique DAC driver can be compatible with FiiO DAPs including X3, X5, X3II, X5II and X7. For X3, X5, X5II and X7 users, you can just uninstall the old DAC driver and install this new driver to use directly, if you’ve ever installed. But for X3II users, please kindly update your device to FW1.6 and then install the new DAC driver.

Note: Rather than the FW1.44beta, the new firmware FW1.6 is upgraded based on the official FW1.4. Compared to the FW1.4, the main changes on the FW1.6 just include 2 points: 1.Be compatible with the new DAC driver and 2.Disabling the OTG function. So some new functions on the FW1.44beta are not available on FW1.6.
