====== SVXLink Reflector + portal + live broadcaster ====== ===== Loopback sound interfaces ===== To redistribute your reflector content to icecast, you'll need to set up loopback sound interfaces. The following file will be used to create 3 loopback interfaces at boot time. It shall be placed in ''/etc/modprobe.d/'': options snd-aloop enable=1,1,1 index=10,11,12 Then run the following command: echo "snd-aloop" >> /etc/modules The code above takes care of boot time configuration. To add the interfaces without rebooting, run the following:

(lsmod | grep snd_aloop) && modprobe -r snd_aloop
modprobe snd-aloop enable=1,1,1 index=10,11,12

You need to adjust the ''enable'' and ''index'' parameters to insert additional interfaces. ===== Icecast ===== Install ''icecast2'' from repository. Below, you'll find the configuration file to install in ''/etc/icecast2/'' after having changed the passwords. Region Auvergne-Rhone-Alpes icemaster@localhost 100 10

===== SVXLink (listener) ===== ==== Installing ==== We'll use the other packages generated in the section above. Go back in ''/usr/local/src'', and run the following commands:


dpkg -i svxlink-server_*.deb svxlink-gpio_*.deb libecholib1.3_*.deb
apt-mark hold svxlink-server svxlink-gpio libecholib1.3

Alternatively, you can choose to use the packages from the repository, which should be the same, since we didn't patch their codebase.


apt install -y svxlink-server
