Hm, sounds like you don't have an audio device selected. Can you check the preferences and list your sound API, latency, and devices selected?

Hm, some disturbing news about the USB implementation in raspberry pi:

It looks like there might be trouble for USB controllers that draw their power from the device. A dedicated hub or a controller powered by an external supply might be necessary.

Hi, neufena! Can you post your compile commands?

I use Mixxx on a Raspberry Pi 3 with Raspbian.
I only use ALSA, because PulseAudio crashes.

The repository version is version 1. Which is a problem, because in that version, you can't use a splitter cable to split stereo in prelisten-channel and master-channel.

You can select a non OpenGL-using waveform display.

The default audio output works for Audacious, but somehow on Mixxx it's horrible. Therefor, I use an external USB-soundcard. That seems to improve the general speed in Mixxx also (otherwise, the analysing of tracks would take too long and song play would slow down).
Since I can't use a splitter cable, I tried 2 external USB-soundcards but for now, that crashes my system.

I think you could use JACK for the splitsing stuff, but I didn't find out how yet.

Any hints on how to update Mixxx to version 2?
On how to use JACK to split left and right channel for use with a splitter cable (Griffin).

I'm not very familiar with Raspbian or Debian, so I don't know if there are more up to date Mixxx packages for ARM. You may have to compile it yourself.

Generally, using one sound card with 4 channels of output is recommended because it is most reliable and easiest to configure. It is weird that using two USB sound cards crashes your system. Can you provide more information? Does Mixxx crash or your whole system? Could you attach your ~/.mixxx/mixxx.log file from after that happens? What sound cards are you using?

As for setting up JACK to use a splitter cable, you can do it with QJackCtl by routing Mixxx's master and headphones outputs to only one channel each of your sound card instead of going to both channels.

Hi all,

If you're having problems with Mixxx, this seemed to work on RPi2/3:

https://gist.github.com/fayaaz/8800d520 ... 1a54c5b6c0

Code: Select all
sudo apt-get install libjack-dev libjack0 portaudio19-dev
sudo apt-get build-dep mixxx
sudo apt-get install g++ git scons libqt4-dev libqt4-sql-sqlite libportmidi-dev \
  libopusfile-dev libshout-dev libtag1-dev libprotobuf-dev protobuf-compiler \
  libusb-1.0-0-dev libfftw3-dev libmad0-dev \
  portaudio19-dev libchromaprint-dev librubberband-dev libsqlite3-dev \
  libid3tag0-dev libflac-dev libsndfile-dev libupower-glib-dev
sudo apt-get install libfaad-dev libmp4v2-dev
git clone https://github.com/mixxxdj/mixxx.git
cd mixxx
scons -j4 optimize=native opengles=1 machine=armhf faad=1
sudo scons -j4 install


The speed of analysing files on the RPI leaves a lot to be desired but I got two USB soundcards (ODAC for main output, Numark Mixtrack Pro for headphones) to work fine and everything was responsive.

Thanks Fayaaz. I made a note about those scons arguments on the wiki.
