Update:
The speakers have one subwoofer and two woofer/tweeter units operational. Music library accessible.
The cable for the TV tuner card for the computer does not fit in the TV socket on the wall. The TV is not operational.
The Audio input for the speakers does not fit in my phone (i.e. FM radio, music player). The radio is not operational.
The mobile internet has some connectivity, but is sometimes really slow (especially for the cellar
) Audio streaming over the net is successful. Video streaming has variable success.
Why is it that so many things don't plug into other things. C'mon, planet Earth, what is it with you monkeylings? Get it together.
