    I use squeezebox server with an USB DAC and the official 7″ display. Sound is not good and I can hear cracking sound.

    I have the feeling that since I installed the display sound is not good.

    Everything is updated to last version. Alsa parameter is 80:4::

    Thanks for helping

    Hi Anthony,
    You can try activating the max-USB current to give your USB-DAC more power. What power supply are you using for this setup? We recommend a 2V supply.

    I use a 2.5V supply that’s why I am surprised. I don’t know whether my crackling sound is due to power supply or not.

    I will try to activate max usb current

    Unfortunately no changes with this option. It says it changed arm frequency. Is it over clocking ?

    Hi Anthony,
    The frequency only changes for the first new start, no problem there. Please try using the parameter „-o hw:1“ for sound output to circumvent any software problems. Please also try using shairport and other test files to rule out the files or player as a source of error. Finally, you might try giving the USB separate power supply with a powered USB-HUB. However, we have not had great experience with USB-DAC’s overall and recommend I2S native sound cards in general.
