New to JamKazam and no audio even on setup

Hi Charlie,

Annoying not to be able to get it going.
Now, from your two times remark "no sound/audio on/from the mac", I'm under the impression you are expecting your mac speakers/headphone output to give you your JKZ return audio signal?
If so, that is not how the signal is supposed to flow. Your headphones should be attached to the headphones output of your Focusrite.
In JKZ you choose your Focusrite as both input and output device.

And do bear in mind that you will only hear your 6i6's output when either in 'audio gear setup [play] test' or when 'in a session' - when everything is setup correctly, so 'local monitoring' switched off. (USB playback only)

NB - the 'record' button is rather nondescript in its functioning. It will record - when pushed in a session - and save its results when 'stopped'. It is not however, any means of testing your success in setting up your gear.

Thanks Dimitri, that makes sense.  I assumed JamKazam had a way of playing back from the laptop.  I don't have the right kind of headphones but will get some so I can monitor.  I'm still puzzled about playback though - once I've recorded some music, does that also play back through the Focusrite?
