    Hi,

    I cannot play DSD256 with DoP to my external usb dac (Denafrips ARES with XMOS XU208 USB Interface). Is this a limitation of ALSA or am I missing something. DSD64 & 128 play fine. I am using LMS 7.9 with dsd player plugin.

    Thanks

    From another discussion, courtesy of DrTone:

    DOP is dependent on PCM frequency. 384kHz can only do DSD 128 DOP.

    Your DAC would need to be a 768kHz PCM capable DAC to do DSD 256 DOP. 512 isn’t possible via DOP.

    My dac is capable of playing 256 DSD via DoP(under windows for sure). I don’t know if it is a linux or squeezebox limitation.

    Hi vj,

    Should be the former. A proper windows pc can probably handle it, but a Pi should be bottle necked at 128. Still, you can try adjusting some Raspberry Settings like max USB current or CPU, but no guarantees there.

    No worries. Thank you
