Have you updated the USB MCU Firmware to v3.12? The USB MCU firmware v3.12 was release in Dec 2021. It increased the resync time, optimised driver handshake with the USB host(computer/streamer), reduces the USB out of sync issue, and improved compatibility and sound quality. We highly recommend you to update the firmware - if you use the USB input of the DENAFRIPS DDC/DAC. The firmware can be updated via a Windows / Mac computer. Guide: https://www.denafrips.com/firmware-update-usb https://www.denafrips.com/usb-mcu-firmware-update-mac What is a USB MCU firmware? The firmware is a piece of software that 'flashed' into the microprocessor (MCU/CPLD/FPGA/etc). For the case of USB MCU firmware, it flashed into a STM32MCU uProcessor, hence, the uProcessor will be programmed to work as a USB Audio Receiver. Driver on the computer (Windows/Linux/Mac) is another piece of high level software that allow the computer to detect the USB Audio Receiver and communicate with it. *For Mac / Linux streamer, there is no need to install additional driver as it's built-in in the OS. For Windows, the Thesycon driver is required.
