I had some requirements:

* Works on my xbox
* I can jam while working out at gym (android phone)
* I don't want anything complicated/heavy
* I just want to stream via wireshark vpn connection

## Install

sudo apt-get update sudo apt-get install mpd mpc

## Configure

edit `/etc/mpd.conf`:

```
music_directory         "/media/root/BackupRAID/mpd/music"
playlist_directory              "/media/root/BackupRAID/mpd/playlists"
user                            "mpd"
group                           "mpd"
bind_to_address "0.0.0.0"
audio_output {
       type            "httpd"
       name            "My HTTP Stream"
       encoder         "vorbis"                # optional, vorbis or lame
       port            "9000"
       bind_to_address "0.0.0.0"               # optional, IPv4 or IPv6
       quality         "5.0"                   # do not define if bitrate is defined
#       bitrate         "128"                   # do not define if quality is defined
       format          "44100:16:1"
       max_clients     "0"                     # optional 0=no limit
       always_on       "yes"
}
```

binding to that address instead of just localhost so i can connect via wireshark
(vpn)

should I use always_on so doesn't mess up when skipping songs or whatever
sometimes? i notice this is an issue where the stream just stops. very annoying.

Let's create a `mpd` group we can add users to and then add our user to it (to
be able to copy over files):

```
sudo groupadd mpd
```

also create the dirs:

```
sudo mkdir -p /media/root/BackupRAID/mpd/music
sudo mkdir /media/root/BackupRAID/mpd/playlists
sudo chown -R mpd:mpd /media/root/BackupRAID/mpd
sudo chmod -R 775 /media/root/BackupRAID/mpd/
```

I added a user to the mpd group:

```
sudo usermod -a -G mpd baudrillard
```

Now on client machine I could do this:

```
rsync -av --chown=:mpd --delete /home/tilde/Music/ [email protected]:/media/root/BackupRAID/mpd/music/
```

Once it finishes copying:

sudo systemctl restart mpd

if you need to you can use mpc update or sudo systemctl status mpd

firewalling:

sudo ufw allow 6600/tcp comment 'MPD streaming access' sudo ufw allow 9000/tcp
comment "MPD HTTP streaming"

Be careful, because if you allow people to listen to your stream/your stream is
exposed to internet, that will let anyone listen to your internet radio station,
which is generally illegal depending on what you're streaming.

### Weirdly complicated side quest: hdmi output from server

**These are just notes. I haven't actually figured this out yet.**

if you actually want to add an output for speakers connected to the server you
can add another block. For me I wanted it to output via HDMI. I ran this
command:

```
baudrillard@simulacra ~ % aplay -l

**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC233 Analog [ALC233 Analog]
 Subdevices: 0/1
 Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0]
 Subdevices: 1/1
 Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 7: HDMI 1 [HDMI 1]
 Subdevices: 1/1
 Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 8: HDMI 2 [HDMI 2]
 Subdevices: 1/1
 Subdevice #0: subdevice #0

 Subdevices: 0/1
 Subdevice #0: subdevice #0
card 1: NVidia [HDA NVidia], device 7: HDMI 1 [HDMI 1]
 Subdevices: 1/1
 Subdevice #0: subdevice #0
card 1: NVidia [HDA NVidia], device 8: HDMI 2 [HDMI 2]
 Subdevices: 1/1
 Subdevice #0: subdevice #0
card 1: NVidia [HDA NVidia], device 9: HDMI 3 [HDMI 3]
 Subdevices: 1/1
 Subdevice #0: subdevice #0
```

then edit my config/add this block:

```
audio_output {
   type        "alsa"
   name        "RX-A1080 HDMI Output"
   device      "hw:1,3"       # or "plughw:1,3" if you need automatic format conversion
   mixer_type  "software"     # software volume control
}
```

I will also have to disable pipewire otherwise pipewire will take control of the
device. you probably don't want ot do this if you're not on a server set up/are
using a desktop or something where you like to produce sound. an alternative
setup would be to use mpd in user mode.

```
systemctl --user stop pipewire.service pipewire.socket
systemctl --user stop wireplumber.service
systemctl --user stop pulseaudio.service pulseaudio.socket
killall pipewire
killall wireplumber
killall pulseaudio
lsof /dev/snd/*
speaker-test -D hw:1,3 -c2
sudo usermod -a -G audio mpd
sudo systemctl restart mpd
```

to trouble shoot i also enabled the log in the config and then:

```
sudo touch /var/log/mpd/mpd.log
sudo chown mpd:mpd /var/log/mpd/mpd.log
```

i could restart mpd and use `sudo tail -f /var/log/mpd/mpd.log`

## Client

sudo apt-get install ymuse

It might be confusing but this will basically just be like a remote control and
you listen to http://10.1.0.1:9000 for the stream.... it's the same for malp on
android (fdroid) which use vlc to stream fine...

## Bonus

On my server I like to also run projectM while just listening to the http
stream...
