I have been unsuccessful in getting it to record from speakers, but I did find that if I selected OPTIONS/AUDIO OPTIONS/OPTIONS FOR MICROPHONE
Make sure the correct microphone is selected, then click on the VOLUME button and click SELECT in the microphone box
Then I could record by sticking the mike up to the speakers.
Once I recorded internally, but the sound was patchy and couldn't understand anything, haven't managed to resolve this yet.
Hope this help someone
