    Hi dear M2P community,
    I’m using a Rpi Zero with a Hifiberry mini Amp.
    Fresh install of the latest M2P version.
    YMPD as Player.
    When trying to change the volume, the error „problems setting volume“ occurrs.
    I found several posts to this topic in this forum but none solved the problem.

    Settings in M2P and mpd.conf say:
    Soundcard: default – snd_rpi_hifiberry_dac
    Aufioformat: 192000:24:2
    Mixer device: hw:1
    Mixer: Digital (I also tried Software)

    alsamixer says: „This device has no mixer“ – sounds a little disturbing for me.

    How can I solve the issue?

    Many thanks and best regards
    Muhackl

    Hi,
    I contacted Hifiberry support.
    To get this to work, you have to add/change the following to/in the /etc/mpd.conf

    audio_output {
    type „alsa“
    name „sysdefault:CARD=sndrpihifiberry“
    mixer_type „software“
    }

    As the Hifiberry Mini Amp does not support either Digital or Hardware (or Master) volume control via ALSA.

    Hi,

    I’m having the same problem using a Raspberry Pi Zero W + HiFiBerry MiniAmp. There’s no sound coming out of the attached speaker (Tivoli Dual Alarm). I chose „HiFiBerry Dac+ Light“ as the Hifi Berry driver and also configured the MPD player as stated above. MPD players says „problems setting volume“. I have no clue what to do next. Actually, I only want to use the hardware as a shairport player. If there is no support from your side, I will probably change to the piCorePlayer which is recommended in the original article on the HifiBerry site. Still, helpm is appreciated.

    Here’s the debug output:

    Hi macpac,

    The miniamp does not support hw volume controlso MPD does not have dynamic volume config.

    But you need shairport as your player anyways if you prefer AirPlay. Just select „simple airplay“ in the HiFiBerry plugin, reboot and you should see max2play as an AirPlay device.

    Hello Heiner,

    I tried this way before and only had a look at the MPD player to check whether the MiniAmp works. Anyway, I now followed your advice and chose the „simple airplay“ configuration. I then activated squeezelite and shairport in the Audioplayer menu and synchronized this player with my other one which runs on the same Raspberry Pi as the squeezebox server in the server’s menu. Shairtunes2 is not installed/activated. Still no sound. I switched the output channels‘ connection to the speaker but still no sound. What now?

    Herw’s the debugging info from the audioplayer menu:

    Hi macpac,

    If you have a Squeezebox Server running, do you not use shairtunes2?

    In any case, you have the same output for both players, so they cannot run simultaneously. Try selecting default_hifiberry for one of them.

    If there’s still no sound, select „none“ in HiFiBerry, reboot, reselect the light and reboot.

    Hi Heiner,

    I tried your tips but as they still didn’t work out, I used the piCorePlayer. Here its’s the same problem.

    So, it must be a hardware problem with the speaker… As I understood, the speaker needs no extra power but only needs to be attached to the MiniAmp? MiniAmp + Raspberry Zero work with 5V, 2A.

    Hi macpac,

    The power supply is probably too weak. We recommend using a 5V 2.5A PS for the Raspberry Pi 3 with a sound card HAT in general. For the MiniAmp it might even be recommendable to use 3A.

    Also, make sure the speakers you use are only around 3W each as that is the maximum capacity of the miniamp. What wattage do your speakers have?

    Hi Heiner,

    well, I only use the Raspberry Pi Zero W model + MiniAmp as described in the guide. The recommendation there is to use 1.5-2.0 A. The speaker is only described as a ‚3″ full range driver‘ but according to the guide the 2A should be sufficient to power the Raspberry Pi Zero W model + MiniAmp + 2 speakers! I will test the speaker next with another amplifier…

    Hello Heiner,

    meanwhile I found out the following: The speaker needs 5W and it works fine when being attached to my stereo’s amp. But what can I do now with my light configuration which hasn’t sufficient power? As I only need a mono signal on the speaker, would it help to use both channels to double the power? Any other idea?

    Regards, macpac

    Hi macpac,

    Sorry about that, but with 5W you should at least get some output from the MiniAmp. If possible, I would advise you to try out another speaker in the same range to make sure they are not the whole problem.

    Hello Heiner, I tried another speaker. There is still no sound, just a cracking sound when connecting…

    Hello again,

    the problem was solved. Opposite to what the construction guide says, soldering (not just fixing) a header on the Raspberry Zero W seems to be required. I bought a Raspberry Zero WH instead and everything works fine now. 🙂

    Hi macpac,

    Thank you for the follow-up. I am glad your setup is working now 🙂
