    Anyone using a Topping D90 DAC with PiCorePlayer on the USB port ? .............

    Could you tell me the Output Setting for Squeezelite ?

    I've ordered a Topping D90 and it will save me the trial and error method of figuring out the output setting.
    Thanks!

    I got my Topping D90 DAC today and in Case anyone needs to know the output setting that works, it is:

    hw:CARD=D90,DEV=0

    Just a little more insight.

    The pCP help doesn't include the comments the system provides about the various output settings. These can be displayed using the aplay command and provide a little more information. For the Allo DigiOne card the output is below.

    The only setting that appears to provide direct pass-through to the device is the hw: setting, as suggested by pCP in the help. All other settings apparently route the audio through some level of software or DSP processing first, and then on to the device. From a fidelity perspective it seems that the hw: setting is the correct one (as you noted in your post).

    Code:
    ~$ aplay -L
    null
        Discard all samples (playback) or generate zero samples (capture)
    default
    plugequal
    equal
    sysdefault:CARD=sndallodigione
        snd_allo_digione, Allo DigiOne HiFi wm8804-spdif-0
        Default Audio Device
    dmix:CARD=sndallodigione,DEV=0
        snd_allo_digione, Allo DigiOne HiFi wm8804-spdif-0
        Direct sample mixing device
    dsnoop:CARD=sndallodigione,DEV=0
        snd_allo_digione, Allo DigiOne HiFi wm8804-spdif-0
        Direct sample snooping device
    hw:CARD=sndallodigione,DEV=0
        snd_allo_digione, Allo DigiOne HiFi wm8804-spdif-0
        Direct hardware device without any conversions
    plughw:CARD=sndallodigione,DEV=0
        snd_allo_digione, Allo DigiOne HiFi wm8804-spdif-0
        Hardware device with all software conversions
