Musical Fidelity TriVista 21 DAC not working with a K22: what am I missing?

I’ve found out that the chipset in this DAC either does 96 or 192, and nothing else. The toggle switch on the DAC switches between the two rates, but I’ve been leaving it at 192.

I am able to use my favourite filters in HQP, which is great. I’ve set sample rate in HQP to Auto, which works OK, and rate limit to 176. I’ve tried 192 in rate limit, but the DAC won’t lock on to that. The max it will lock on to is 176. I don’t understand why that is, when technically the DAC can support 192.

I will address the above first.

It can’t be true that it only supports 96 or 192 if you can get a lock at 176.4. I wonder if those two settings apply more to how it processes internally. Might it govern built-in upscaling so that it scales 44.1k to one or the other? I’m on a lunch break now so my time is limited otherwise I’d try to read up on it.

Question: Are you able to get a lock at 96k? This would help me make sense of it.
