I have a set ot Sony speakers (SRS-X77) which I've used for some years with my Mac Mini, without a problem. Recently, even though the computer tells me that it's connected to the speakers, no sound comes out and I usually have to make the computer "forget" the speakers and then find the again.
Can anyone explain what is going on please? I have to say that I often find Bluetooth a most unreliable way of doing stuff.
