I know, thank you. I did re-flash amanero CPLD and firmware many times. Problem is related to DAC firmware I suspect.

Seems like it is not. If "Amanero ASIO Combo384" selected as asio device in transcoder then error occurs, see it in attached pictures.

Yes it does, track time in the FB status bar runs as it supposed to. But no sound if "ASIO : DSD Transcoder (DoP/Native)" selected as output device. I am starting to suspect DAC firmware corruption. However, I wasn't able to find any information in web about issues with firmware in Buffalo-IIISE PRO DAC.

maybe is device firmware need different asio drivers Seems like it is not, after choosing "Amanero ASIO Combo384" as asio device in transcoder, it gives error, see in attached pictures.

Thank you for advice but situation got worse after installing SetupASIO64_109.msi DSD does not play anymore even with default driver. I've attached the trace output file, maybe Maxim could help to figure out what is going on.
