Have you verified that your soundcard is actually outputting at 176kHz or 192kHz? Are you using the Kernel Streaming soundcard interface for MPX Output, and not DirectSound or Wave/MME?
In case anyone (else besides Jesse G.) is watching this thread…
I receive RDS data via Spinitron, which means it's IP dependent. I have (eventually) discovered that our IP provider changed our IP address… right around the time I was testing this out end of August.
So that has confounded my testing. My base system running RDS is working now, so now it's just a matter of testing out BaOne.
