It`s all about DSD & MPD

[Ran]

Which DAC? What version of MPD? Paste your conf file and read this:

Good luck!

Change "dop" to yes.

FYI:

dop on - This will enable DoP protocol and will send the DSD data encapsulated inside a PCM container (Some CPU utilization)
dop off - This will transcode DSD into PCM by MPD for non DSD enabled DACs (High CPU utilization)
#dop - This will send native DSD to a native DSD enabeld DAC

It all depends on your DAC.

dop off - This will transcode DSD into PCM by MPD for non DSD enabled DACs (High CPU utilization)
#dop - This will send native DSD to a native DSD enabeld DAC

Not exactly correct. dop=off is the same as not specifying it at all.

dop=off will just disable DoP, but will not affect native DSD. Native DSD is used whenever it is supported (by the ALSA driver).

If I have a DAC that supports native DSD, how will MPD know to send the DSD stream as is without trying to transcode the data into PCM?

MPD asks ALSA. ALSA needs to know. I don't know how it knows, and how you configure it, but that's outside MPD's scope.

Hi! How in new version 0.20 (not yet released) using dop option?
I so in
https://bugs.musicpd.org/view.php?id=4546

MPD 0.20 (git master) supports both DSD_U32_BE and DSD_U32_LE.

How it work?

If my DAC support native DSD_U32_BE or DSD_U32_LE i need to use

Code: Select all

dop = off 

?
