Hi, I am still working on the AudioExtender, for now I copied my Entry from the HackSpace Siegen wiki. Once I find time, I will translate it.
I finally got the playback working. You can find my software here: LAES@github
discovering devices is working
playback with multiple extenders
Audio Extender made by devolo
RCA and mini-TSA connectors
data over powerline (Homeplug AV, 85Mbit/s)
on ebay for around 10€
3 Leds, Power, Lan, Connected to Server
works only up to vista
works only for 32bits
no linux version
uses a virtual soundcard to pipe all audio to the extender
Audioformat: PCM, Stereo, 44100, 16bits signed
shoutcast server on 12000
apparently command channel on port 12001, nothing know yet
communicates with the extender by http and cgi
streamer.cgi?cmd=srvstart to start playback etc
Some stuff I captured with wireshark to base my program on. Be careful, the ips may vary! I try to alter the ips to fit:
Right now I have a python script in place which is able to discover the Audio Extenders by broadcasting a special message (the audio extender must be paired with your network beforehand, I most likely will not look into this)
This is all work in progress and not meant to be used by a end user but for testing purposes.
I am also working on the streaming part by right now I haven't figured out how to buffer the data correctly leading to a DDoS of the device which need a reboot to work again.
