Indeed, I checked my DAC specification and you know what: it's input is limited to 96 KHz ! I should have checked that before asking. Sorry for the trouble... I just made a trial with an other DAC that someone lent me. The specification of that one tells that it does accept 24/192 streams, and indeed, it works ! > There is no error because 24/192 streams in itself work fine, and DAC > chip on audio card can process that stream - it's just that there is > trouble either sending it through S/PDIF or receiving by external DAC, > which is outside of the scope of your card, so there is no error. The conclusion of all that is that the Xonar DX works perfectly with Linux and Alsa and allows playing any sound file from 16/44.1 to 24/192. Thanks again to you.
