This was working fine for me yesterday, but when I sat down today I'm not getting any audio from the headphone port of my Axe I/O.
I've tried using Amplitube 5, I have the input and output both set to Axe I/O. When I play guitar, I see the input and output levels move up and down as expected in Amplitube, but I get nothing through the headphones. I have the headphones volume set to 12 o clock and the monitor set all the way to "DAW".
I have tried other apps, eg. watching a youtube video with the system output set to the Axe I/O, and again I get nothing on the headphones.
I have tested the headphones by plugging them directly to the computer and they work fine.
I'm using a Mac Mini with OSX 10.14.6. I've rebooted everything multiple times.
Any suggestions are greatly appreciated! Thanks.
