internal speakers don‘t work after using external speakers
after I had connected my Macbook Pro to a network audio receiver via my private wlan, the internal speakers of the Macbook don‘t show up anymore under the speakers symbol on the topline next to the clock.
Even if it‘s not connected to the network, there doesn‘t come any sound out of it.
Just if I restart the laptop I hear the short Apple Orchester sound. & after that, it stays quiet.
So the speakers do work & the problem seems to be located somewhere else.
Does anybody know what the problem is?
