window development – Microsoft Q&A

The current demo implementation idea is to refer to Microsoft’s sysvad’s miniport Twavert stream -> buffer->usb driver stack for timed transmission and sending.Is the above implementation architecture correct?

The adoption of the above-mentioned architecture introduces buffer delay and urb delay during transmission, resulting in excessive end-to-end delay triggering

The Audio end-to-end Latency use case of the Communications Audio Fidelity test item failed.

May I ask if you could offer some optimization suggestions?

The following errors will occur in the hlk test，I want to know how to report Latency？
