Add Audio Track Does Nothing

[Scott_Graham]

I had this same issue and solved it by matching Jamkazam’s sample rate to my audio interface’s sample rate.  To find your audio interface’s sample rate, connect it to your Mac and go to Applications > Utilities > Audio MIDI Set-up.  When you click on your audio interface, it will show its sample rate (mine was 44.1 kHz).  Then open up Jamkazam, delete your audio hardware and reconfigure it as you have been doing.  When you get to the screen that asks you to choose your inputs and outputs, if you look on the right hand side towards to bottom you’ll see a place to choose a sample rate from a drop-down menu.  Choose the value that corresponds to your audio interface’s sample rate, go to the next screen and you should be able to add tracks. 

This worked for me, hope it works for you!

Good idea, but unfortunately no change in the problem. Not even after the JamKazam update today.

I just had a little progress here - unless it was caused by the Jamkazam update you refer to (I didn't see any notification of this).  I found under the Manage menu (top left), under Audio Settings->Configuration->Reset Audio Configuration, that after I did this, that I did in fact get the one audio track to come up.  Unfortunately, after selecting my instrument (also a double bass) that it didn't seem to take the configuration - there doesn't seem to be any "Save" button associated with this dialog; just a "Close" button.  So, after clicking on close, the instrument is still empty.  However, it is some minor progress, and perhaps may provide some clues.  Perhaps give it a try, maybe it will solve your problem.
