    LMS/Squeezelite streaming DOP when it should be doing native DSD?

    Hi there!
    I'm using LMS 8.2.0 / Squeezelite on Vortexbox with a Topping D10 DAC.

    I noticed that when playing DSF/DSS files, the Alsa process shows

    [root@player ~]# cat /proc/asound/D10/pcm0p/sub0/hw_params
    access: MMAP_INTERLEAVED
    format: S32_LE
    subformat: STD
    channels: 2
    rate: 176400 (176400/1)
    period_size: 1764
    buffer_size: 7056
    When, I guess, it should show something related to DSD on the format entry.

    The DSDPlayer config page shows

    This player supports native playback of DSD files. DSD-over-PCM should be configured on the player configuration interface.
    So, Native DSD is detected for the D10 dac.


    Furthermore, on the Advanced > File Types configuration page, the DFF and DSF file types are configured as Native for the DSF and DFF streams and as dsdplay for Flac streams. Could this be the culprit? I find this configuration page a bit cumbersome.


    The Audio device for squeezelite has the following options set: front:CARD=D10,DEV=0 -D 250


    Can anybody shed some light here?

    You can try this: front:CARD=D10,DEV=0 -D 250:u32le or front:CARD=D10,DEV=0 -D 250:u32be
