This is a barebones, basic setup which should be enough for you to play around with and hit the ground running.

For expediency and testing purposes, we assume it's all being ran from the same machine. Also assuming you're a respectable individual using Linux... ;-)

# Install them

In a terminal on Debian / *buntu:

sudo apt update && sudo apt install icecast2 mixxx

Make sure the Icecast daemon is stopped before continuing:

sudo systemctl stop icecast2

# Configure Icecast

You need to change the default usernames and passwords.

Edit the icecast.xml configuration file. Use any text-editor you're comfortable with.

In a terminal:

sudo emacs -nw /etc/icecast2/icecast.xml

Scroll down to <authentication> section to configure passwords and users.

Optionally also scroll down just a bit farther to <listen-socket> / <port> section and set an alternate port.

Save the file (in emacs: Ctrl+X Ctrl+S)

(Protip: Don't reuse credentials shown in example as they're in every password dictionary...)

# Configure Mixxx

Now, open Mixxx. On first launch, it'll prompt to setup audio hardware. Do so.

Depending on audio subsystem, hardware, and config, it can be tricky...

First, try the "Query Devices" button; let it probe I/O. Hopefully all fields are populated...

If not: for Master Output, try "pulse" "sysdefault", or "default" respectively.

Edit: select dual channel output (1+2).

Click Apply.

Output is all that's needed for basic operation. Feel free to configure and test inputs, microphones and the like later on.

# Load your library

If all went well in the last step: Click the Library tab on the left and Add directories containing your audio files.

Click Apply.

At this point, one might consider playing a file from a deck to make sure audio is configured properly... You'll first need to update the library to do so: click "Library" from the Menu Bar (not the preferences window), then rescan library.

# Mixxx to Icecast

Now, in the Preferences window: Click "Live broadcasting" tab on the left. Here you plug Mixxx into Icecast.

Create a new connection with something similar to the following:

Type: Icecast 2

Host: Domain or IP pointing to the icecast server. Since they're both in the same machine, use "localhost".

Login: username used for server. default is "source"

Mount: mountpoint configured in icecast.xml. Default is "/stream"

Port: port where icecast listens/broadcasts from; configurable via icecast.xml

Password: password configured in icecast.xml

Optionally configuring the encoding options, metadata and other settings here are not required for operation, but are recommended.

Click Apply > OK.

# Restart Icecast

In a terminal, resurrect the daemon:

sudo systemctl start icecast2

Navigate to domain/IP + port of the icecast server in a Web browser to verify Icecast is running. (e.g. http://example.com:8080)

# Finishing up

In Mixxx, load files from your library into your decks (drag n' drop, or via right-click).

Click the the live broadcast button, which looks like a satellite dish, or use CTRL+L .

If no error message shows up: you're now streaming into icecast.

Press play on a deck.

Jam out!

You can toggle the Auto DJ feature to queue up tracks automatically for unattended operation.

To listen to the stream, plug the Icecast URL into media players like Transistor, VLC, or even a Web browser like Firefox.

Also recommended to setup Dyn-DNS or something via Afraid.org if planning to connect remotely. Icecast server also runs very happily on modest hardware such as a Raspberry Pi.

Possible to feed audio from a mobile device to the machine running Mixxx over a bluetooth audio sink if you wanna deal with the headaches of wrangling those pulse audio connections.

Happy Hacking!

I hope one of you is a *nix power user, and can help me out.

I was trying to get mixxx to work with shoutcast, and in the process not only did I manage to break mixxx (it says there's no sound device configured, and I can't find a solution anywhere online) but I also managed to break audacity.

So when I try to launch audacity from the menu, it just doesn't start. When I try to launch it from the cli, it fails with an error message: audacity: symbol lookup error: audacity: undefined symbol: PaAlsa_GetStreamInputCard

But if I use this to start it, audacity works normally: LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/ audacity

So I presume that I messed up my PATH somehow when I was trying to get mixxx to work, and I wonder if anyone who knows how to interpret this information can help me fix it, so I don't have to use that expicitly-defined LIBRARY PATH to start audacity from a terminal?
