USB audio data transmits information as packets rather than a continuous stream of PCM audio and also requires a clock signal to keep everything in time when the data reaches the DAC. After USB transfer, data packets are decoded into a single audio data stream format that a DAC understands, such as I²S. The choice of clock system is actually very important for USB …
How to transfer data to USB isochronous endpoints ...
https://docs.microsoft.com/en-us/windows-hardware/drivers/usbcon/transfer-data-to-isochronous-endpoints
A Universal Serial Bus (USB) device can support isochronous endpoints to transfer time-dependent data at a steady rate, such as with audio/video streaming. To transfer data, the client driver issues a request to read or write data to an isochronous endpoint. As a result, the host controller initiates an isochronous transfer that sends or receives data by polling the …
