I'm not sure if this is the best place to ask this. I have a Nano running under Windows 7 pro 64-bit and the latest Crimson drivers. I connect the Nano to a NAD M51 DAC and connect the HDMI output of the M51 to my 1920x1200 Samsung monitor. Everything appears good except the highest audio format Windows offers me is 176.4 kHz, not 192 kHz. The NAD M51 is supposed to be capable of 24/192 kHz. What do I have to do to get 192 kHz as an audio option? Maybe it's Windows or maybe it's the Crimson drivers. Maybe it's the Nano, maybe it's user error, or maybe it's just the rum?
