I have an Acer Aspire 5740 laptop with an Acer USB port replicator. The OS is Windows 7 Home Premium.
Until a hour or so ago I had the sound coming out of the USB speakers connected to the port replicator and I could use the usb microphone also connected to the port replicator.
As I am about to take my laptop on holiday (it's worked so hard lately I thought it really deserved one!) I tried out a headphone set connected via the two jack plugs and found that it worked satisfactorily.
Now I find that the sound comes from the internal speakers and only the internal microphone works.
How do I switch between the internal and external speakers/microphone?
