I just purchased a D/A converter and some powered studio monitors so that I can use the AES/EBU outputs of the Kona 2. My audio is playing back fine from Both Final Cut and Mac system sounds (iTunes, quicktime, et al).
I don't have any volume control using the Mac volume keys on the keyboard and the only volume control on the speakers are in the back. Is there any way to enable the Mac volume keys so I can turn it up and down??
your Kona has analog outputs for montitoring. Buy a mixer, like you are being told to do. This is what everyone does - this is the correct thing to do. You are not going to use software to adjust your volume.
