# Setup and packages

```sh
sudo aptitude install icecast2 gstreamer0.10-pulseaudio gstreamer0.10-plugins-base gstreamer0.10-plugins-good gstreamer0.10-plugins-ugly-multiverse gstreamer-tools pavucontrol
```

Remember the password when setting up `icecast2` (when prompted by the install
script), because we will use it later on.

# Setup pulse

- Get the name of the monitor pulse source (a fake input stream that is in fact
everything that goes out of pulseaudio mixer). Run:

```sh
$ pactl list
```

and look for a section like:

```sh
  Source #1
    State: SUSPENDED
>   Name: alsa_input.pci-0000_00_1b.0.analog-stereo.monitor
    Description: Built-in Audio Analog Stereo
    Driver: module-alsa-card.c
    Sample Specification: s16le 2ch 44100Hz
    Channel Map: front-left,front-right
    Owner Module: 5
    [...]
```

(note the `.monitor` at the end, this is important). We need the name of the source, which is the thing with a > in front. Copy that.

Then we need to make sure the source is not muted (maybe replacing the source
name):

```sh
$ pacmd
Welcome to PulseAudio! Use "help" for usage information.
>>> set-source-mute alsa_output.pci-0000_00_1b.0.analog-stereo.monitor false
>>> exit
```

# Start the broadcast

```sh
gst-launch pulsesrc device="alsa_output.pci-0000_00_1b.0.analog-stereo.monitor" \
 ! audioconvert ! vorbisenc ! oggmux \
 ! shout2send ip=127.0.0.1 port=8000 password="icecastpassworkd" mount=stream.ogg
 
```

First line capture your pulse output, second line converts it in vorbis, and
muxes it in an ogg container, third line connects to icecast2, and makes it
available.

# Listen

```sh
$ firefox localhost:8000/stream.ogg
```

and play. Of course any music player that supports ogg/vorbis and remote streams
works.
