OK, we're apparently running it at 192kHz. This is supported by the PCM5102 DAC device.

Right now, I am looking through USB specs to figure out how to have the radio
tell the PC that it's 192ksp. In the "Digital Audio Interface Properties" screen, there is a dropdown menu "Select the sample rate and bit depth to be used when running in shared mode". But it's grayed out. This tells me that Windows
should at least be capable of using other bitrates than the standard 44.1ksp.

I found an audio spec on usb.org:



Using Wireshark, I was able to find the exact USB packet where the radio tells
the PC (erroneously) that the sample rate is 44100 samples per second.

AND I found it in the USB teensycore.

Gonna change it now, see what happens.
