Accuphase DAC-50 issue

I am using Accuphase DAC-50, when I use volumio to play the song which the sampling is higher than 16 bit, it does not decode very well, some “g” “g” noise occurred. The song does not play properly. However, when I restricted the sampling to 16 bit, the problem does not occur. I am not sure what is the problem, but hope it can be fixed soon. Thanks.
