The clock fed into the DAC chip has to be a certain multiple of the sample rate, usually 128 or 256. Frequently it can be greater as well such as 512.
Common frequencies for the 48Khz "family" are 12.288Mhz or 24.576MHz. IF the minimum multiplier for the DAC chip is 128, and 12.288 was chosen as the crystal frequency then the system can play up to 96 but cannot handle 192. Even if the DAC chip spec sheet says its 192 capable. If 24.576 was used then it can play 192. So whether a particular DAC implementation can play 192 depends on the minimum clock multiplier supported by the DAC chip and what crystal frequencies are used. I just checked and the DAC chip in the TP has a minimum clock multiplier of 128. So to play 192 it must have a 24.576 crystal. (or multiple) Of course all this is irrelevant if the CPU can't handle the data that fast.
