    Hi again Ralphy and Ronny,
    I forgot to mention,
    Volume does not work with DSD in my configuration.
    Ronny if you could use volume control withe the KTBD, I'd be happy to have the settings that allow this.
    KTBD FW is latest.
    Best, Tom

    Thank you Ronnie,
    that does work with my headphone amp as well ;-)
    just the better part of my cans do not need the extra device to be driven properly, the KTBD output is quite excellent for them (as far as the volume can be controlled - playing FLAC - the Focal Elegia is usally driven by volume 55/100).
    I think for DSD the output needs to be set to 100 in the HW volume control settings (for Windows) to play correctly. Guess its the same for Linux based applications.
    Best, Tom

    Khadas Tone Board DAC - ESS9038Q2M - DSD

    Hi Ralphy, Hi Ronny (put a pic of the dogs in my profile ;-)
    I did change the source of the dsf files to an locally mounted USB-drive, which then allowed me to play small (2min) DSD256 files.
    Thinking it is the good direction, I have now swapped wifi against ethernet, to find out if this is helpful ... and it looks promising with files <300mb.
    Next step looking on bigger file size DSD256.
    Thanks again
    Best, Tom

    Khadas Tone Board DAC - ESS9038Q2M - DSD

    Ralphy, Ronny,
    I think we can close the case.
    Witrh PiCorePlayer it is possible - using the Khadas TBD - to play DSD256 natively via USBmount/Ethernet stream sans degradation.
    It seems to be important to use the correct settings on LMS and SQL.
    That includes:
    - DSDplay plugin with LMS
    - PCP-DSDPLAY.tcz for the PiCorePlayer
    - Set SQL-binaries to Native/DOP DSD Squeezelite
    - mount your USB after installing and enabling add. FS
    - Setting you Media Folder correspondingly
    - Set your Format in Advanced Setting for LMS correspondingly
    - Set your SQL output to USB-Audio
    - Set your DSD settings 0:u32be for the Khadas TBD
    and you are all set to play DSD256 flawlessly via ethernet to your PiCorePlayer

    If you feel you have to add something to that list, pls feel invited to add information
    I'd like to publish that in my next contribution to AS. ;-)

    Thanx galore from France,
    Tom aka Ducktoller

    That's great!

    For a DSD capable DAC, you should always use the hw: prefix in the output settings -o device field.

    If you still experience the occasional dropout or "skip" in the audio;

    set ALSA buffer time to 16384 and ALSA period 4096

    but only if the DAC is connected via USB.

    Thank you Ralphy,
    Unfortunately the squeezelite does not start with these settings plus the KTBD.
    I switched back to the ones used by Ronnie.
    Thank you, have a nice weekend

    Hi Tom.
    Good to see you have it working.
    i think that you will have to find the correct string to use after the hw prefix in your system, and it will probably be different from what Ralphy use.
    So can you post the content of the text that is shown if you press on "more" in the output field on the squeezelite page?

    Steen is correct, I posted the -o for my iOne. My bad for not stating that.

    From the alsacap output from our email thread.

    Code:
    Card 0, ID `Control', name `Khadas Tone Control'
      Device 0, ID `USB Audio', name `USB Audio', 1 subdevices (1 available)
        2 channels, sampling rate 44100..768000 Hz
        Sample formats: S16_LE, S32_LE, SPECIAL, DSD_U32_BE
        Buffer size range from 16 to 262144
        Period size range from 8 to 131072
          Subdevice 0, name `subdevice #0'
    You should use

    hw:CARD=Control

    On my rpi4,

    I use hw:CARD=Control,DEV=0

    for the Squeezelite settings.


    front:CARD=Control,DEV=0 works

    iec958:CARD=Control,DEV=0 also works



    sysdefault:CARD=Control stops Squeezelite

    hope this is useful

    ronnie
