Change the setting to DOP .
Morever when i tried playing DSD on Volumio it was playing fine. Thats my doubt.Please help
RE: Native dsd no working - Tim Curtis - 06-17-2021
Below is the ( i ) help for the DSD support option in MPD Config. There are only three possibilities including Native, DoP or automatic PCM conversion.
Native DSD: If the audio device reports that it supports Native DSD then MPD will send the unaltered DSD bitstream to the device otherwose MPD will perform DSD to PCM on-the-fly conversion.
DSD over PCM (DoP): There is no way to detect if an audio device supports DoP so only enable this if you are certain that the device support it otherwise the encapsulated DSD bitstream may cause loud or unpredictable distortion.
It looks like your audio device does not support native DSD or DoP and the USB connection is limited to only 24/96K. That means that when DSD support is set to "Native DSD (Default)" DSF file playback should automatically be converted to 96K PCM. This is done internally by MPD/ALSA and there are no explicit settings that control this. You could also set SoX resampling to 24/96K which would accomplish the same thing.
You could also reboot and post the Moode startup log and also check the MPD log for any errors.

Iam using ALL KATANA DAC with ISOLATOR and ALLO SHANTI POWER.
WHen playing DSD or DSF file no Proper audio is coming.PLease help if any settings needs to be changed to play DSD or DSF files in ALLO KATANA WITH ISOLATOR DAC.
Native dsd not working for ALLO KATANA WITH ISOLATOR - praveen.sg8 - 06-26-2021
Iam using ALLO KATANA DAC with ISOLATOR Mounted and ALLO SHANTI POWER SUPPLY.
When playing DSD or DSF file no Proper audio is coming(JUst hiss noise with blurred sound).Kindly help, if any settings needs to be changed to play DSD or DSF files while using ALLO KATANA DAC WITH ISOLATOR
RE: Native dsd no working - Tim Curtis - 06-26-2021
Katana supports DSD over PCM (DoP), not Native DSD.
IIRC the first gen Isolator board only supports up to 192K and so limited to DSD64/DoP.
I think the consensus in the Katana community is that the Isolator board is not needed when running Katana with split power.
