Unfortunately you give zero info on your set-up, so no one will be able to give qualified feedback, really.
That said I just switched my S.M.S.L M300MKII DAC from going through a RPi DietPi Roon bridge to a direct USB connection from a WIN10 fanless PC core.
Since I have installed XMOS-drivers, I can now choose between WASAPI and ASIO.
WASAPI allows PCM only with a maximum sample rate of up to 384kHz.
ASIO allows PCM up to 768kHz and DSD up to 512.
No limitation to 96kHz here…
So, to get back to your question, were you able to stream192kHz before whatever update you’re referring to, changed nothing else and now can’t?
Or where are we at here?
Please be more explicit to enable us to help you…
