Hi all,

I had to reshuffle my setup a little and now have a streaming device (a hifiberry) connected to the AUX port of a BS3000. Works well. However, when I select A.AUX on the remote the BS3000 switches on, selects AUX input but obviously nothing plays unless it is streamed (e.g. via airplay) to the Hifiberry. Or the Hifiberry get's told to play an internet radio station.

Now the hifiberry is opensource running on a Raspberry PI. I was thinking that I could monitor one of the Pi's GPIO Pins and once I see it go up (or down) I could tell the Hifiberry to play radio. Or even do more fancy things.

I am not at familiar with the pinout (and it's convetions) on the AUX port of a BS3000. I suspect it would be Datalink, right? Shouldn't it be possible to monitor any of the Datalink pins (provided it is Datalink) to see whether the AUX port is in fact selected? I was thinking about a relay or even something more direct provided it doesn't blow up the Pi.

Is the Link protocol somewhere documented? If it can be decoded and fed into the Pi (I suspect some serial comms forms the basis for Datalink) I could even use the Beo4 to remote control the Hifiberry (V2 of the project :-)

Can any of you B&O tech gurus possibly shed some light on what happens on the AUX port once it get's selected? And what (if any) documentation exists on the protocol used between B&O components? Once I understand that I can possibly work my way from there....

Thanks for any help, comments or pointers anyone may have

cheers
