 - Some Pioneer AVRs use the port 23 default and some are reported to use 8102.
 - `timeout` is a socket level option and should only be configured if you know what you are doing.

+### Source codes
+
+Under these lines, you can find some sample `sources` lists per receiver model. Here we use the source names as shown on the remote as key for each code. However these are for display purposes only, so you could rename inputs to better match your set-up (e.g. `HDMI: '19'` to `Kodi: '19'`.
