Additional Information

To obtain a correct audio, I have to resample my audio into 48000 kHz (not need with my other DAC).
My “very small” issue is for the sound at the statup of the system : I don’t know how to resample it, so each time I stat my system, there is a high mettalic sound !
Thank you for your help.
