Certain I2S drivers in the stock kernel already support up to 384K PCM rate for example the drivers for Allo Boss and Katana DAC's The Katana also supports DoP. These DAC's play DSD64 and DSD128 perfectly.
For other I2S drivers its up to the DAC manufacturer or driver maintainer to release a driver that supports > 192K PCM rate and then get the driver accepted into the Linux kernel.
Thanks for the answer.
Actually, a driver for IanFifo is listed in ver. 4 and ver. 5 moOde. It seems strange to me that latest drivers are less capable then older ones.
Also, there are players (i.e. Gentoo) that support dsd128 from i2s (on RaspBerry Pi) with stock kernel and generic drivers.
I will try to change driver selection to see if there is one which works better with my hardware.
