    ADAU1701 with piCorePlayer?

    Hello,
    I managed to get my ADAU1701 based Sure DAC running on Raspbian, basically using this guide and dto:
    https://digital-audio-labs.jimdofree...01-i2s-driver/
    Unfortunately, I couldn't get this running on piCorePlayer, which is what I need in the end:
    After putting the dto in /boot/overlays and adding
    Code:
    dtoverlay=adau1701-i2s
    to /boot/config.txt,
    Code:
    aplay -l
    returns no soundcards found
    Does anyone know how I could approach this? Anyways, the adau1701 kernel module is there...
    Any help would be great! Thank you!

    What is in dmesg?

    There must be a driver needed. What driver is used in Raspbian.

    dmesg.log
    Thank you for your reply! dmesg attached.
    As I read he dts, it uses
    • simple-audio-card
    • spdif-transmitter
    • i2s

    I do not believe spdif-transmitter is an included driver. You can try to grab it from https://repo.picoreplayer.org/repo/1...modules.tar.xz



    PS, it looks like your wifi country code is improperly set.

    Thanks again!
    I couldn't find it in the given archive
    Maybe I'll give it a try with a new overlay using the pcm5102 codec instead. If it allows slave mode, it should work as well.

    Ok, after replacing the spdif-transmitter with pcm5102a, it worked
    Put my files here:

    Nevertheless, music played via Squeezelite is played too fast, probably a sample rate issue. Is there an easy way to force Squeezelite to resample to 48kHz?

    C-3PO was the answer - now, everything seems to work correctly

    Cool. You can do the resampling client side with squeezelite too.

    Put 48000 in the max sample rate field. (-r)

    The put vLX in the upsample setting. (-R).
