Remarks

Google publishes no digital specification for this adapter; the record belongs to the silicon descriptor alone. From it: a UAC2 device offering 24-bit PCM, with a 16-bit alt beneath it, both reaching 48 kHz, and no DSD path.

The modern audio class, used without climbing past 48 kHz — the ordinary rates, done plainly.
