+===== Configuración =====
+Asumo que airtime esta instalado en un servidor. En este ejemplo el servidor esta en la DMZ y tiene como nombre DNS "airtime.example.com"
+. Editar archivo de config:
+<code>
+sudo cp /etc/airtime/airtime.conf /etc/airtime/airtime.conf.old
+sudo vim /etc/airtime/airtime.conf
+</code>
+Y ajustar la variable:
+  base_url = airtime.example.com
+. Tras cambiar una configuracion, actualizar base de datos:
+  sudo airtime-update-db-settings
+. Editar el virtualhost:
+<code>
+sudo cp /etc/apache2/sites-available/airtime-vhost.conf /etc/apache2/sites-available/airtime-vhost.conf.old
+sudo vim /etc/apache2/sites-available/airtime-vhost.conf
+</code>
+Y dejarlo tal que asi:
+<code>
+<VirtualHost *:443>
+      SSLEngine on
+      SSLProtocol all -SSLv2
+      SSLCertificateFile /etc/ssl/certs/ssl-cert-snakeoil.pem
+      SSLCertificateKeyFile /etc/ssl/private/ssl-cert-snakeoil.key
+      Header always set Strict-Transport-Security "max-age=31536000"
+      ServerName airtime.example.com
+      ServerAdmin root@localhost
+      DocumentRoot /usr/share/airtime/public
+      DirectoryIndex index.php
+      <Directory /usr/share/airtime/public>
+              AllowOverride all
+              Require all granted
+      </Directory>
+</VirtualHost>
+<VirtualHost *:80>
+      ServerName airtime.example.com
+      ServerAdmin root@localhost
+      DocumentRoot /usr/share/airtime/public
+      DirectoryIndex index.php
+      Redirect permanent /login https://airtime.example.com/login
+      SetEnv APPLICATION_ENV "production"
+      <Directory /usr/share/airtime/public>
+              AllowOverride All
+              Require all granted
+      </Directory>
+</VirtualHost>
+</code>
+. Recargar la config de apache:
+  sudo apachectl -k graceful
+. Ya se deberia poder entrar en:
+  http://airtime.example.com

+===== Errores =====
+  * DarkIce: AlsaDspSource.cpp:173: can't set channels [2]
+La causa es que en el archivo de configuración se especifica que el dispositivo puede grabar en stereo:
+  channel = 2
+Y el dispositivo solo soporta mono. Solución:
+  channel = 1
