    Hello everybody,

    I’m having this funny problem that on my latest multi room addition the music sounds like the singers are in a concert hall. I hope you guys find a solution for me.

    Let me explain my setup:

    A raspberryPi 3 works as squeezebox server.
    A couple of Pi2 with amp+ hifiberry’s are working as squeezeplayers
    the latest entry is a Pi2 with amp2.

    The latter works, but as mentioned befor, not so good.

    I guess it is some setting that is not ok, but I don’t know which one.
    In the advanced options from the squeezelite settings I use
    – sysdefault-snd_rpi_h
    – ALSA param: 2000:4::
    – the other fields are blank.

    What do I need to do to get rid of the „echo effect“ on the music?

    Does someone know?

    Hi Joris,

    Please try replacing the ALSA parameter with „80:4::“ and adding „hw:1“ to your command line options (if you do not have your build in audio removed in the Raspberry Settings, if it is removed use „hw:0“). After saving, please also reboot your device.

    Hi Heiner,

    Thx a lot for your help!
    I’ve tried your suggestion (ALSA parameter with „80:4::“ and adding „hw:1“ in command line ) but I get this error:

    Also with HW:0 I get the same. And even an message at the hifiberry page that the soundcard is located at HW:1

    What shall i do now?

    6. August 2018 at 13:40 #36838

    Hi Joris,

    Please try removing the ALSA parameters completely. Also make sure there are no additional blank spaces or any other irregularity.

    6. August 2018 at 13:53 #36839

    Hi Heiner,

    Same result with the ALSA parameters removed. If I leave them in (the 80:4::) and I remove the command line option, then it works again. But with the same weird audio result. The singer sounds like he’s in a big hall or bathroom or whatever.. 🙂

    Please copy your debug info log from the Audioplayer here.

    Hi Heiner,

    I hope you mean this:

    Hi Joris,

    I do, this seems to indicate your sound card is somehow deactivated. Please selecting „none“ in the HiFiBerry Plugin, rebooting, selecting AMP2 again and rebooting once more.

    So after some trying and errors I have now this.

    Unfortunately, still the same weird metallic sounds

    Okay, this output looks good. What power supply do you use for the AMP2?

    8. August 2018 at 18:33 #36881

    I use my ‚lab‘ powersupply. It should be fine.
