Really? Mine just shows 96, but if you have 192 then you could just plug one of these in:
Also I did a quick Google and I found this:
It's confusing. Evidently the hardware is capable of 192 but the OS is limiting the sample rate to 96. My usb-coax converter is 96 on my Mac so I haven't tried 192, but the unused digital (optical) audio out only goes up to 96 in my midi setup app. I am current, 10.6.7 with all updates.
Apple: "The headphone / line output jack accommodates digital optical audio output, analog audio output with a 24-bit, 44.1-192 kHz D/A converter, digital audio output up to 24-bit stereo and 44.1-192 kHz sampling rate and supporting encoded digital audio output (AC3 and DTS)."
