The DAC chip in the Touch WILL do 192 as long as it is given a fast enough clock. The Clock circuits in the Touch ARE fast enough to support 192 with this DAC chip. For the DAC output two things have to be done in the ALSA driver: the DAC chip has to be programmed to run at 192, and the serial interface in the processor that generates the I2S signals has to be programmed to output 192. Programming the DAC chip is the easy part. Programming the serial port on the processor is more complicated. FORTUNATELY its already being done for other sample rates so figuring out which bits of which registers to change is not TOO hard.
