Hi all,
I'm getting intermittent audio drops via USB (MacBook Air 2022 into AxeFX3). Rebooting of AxeFX3 fixes it. Anyone else experiencing this?

I’ve actually noticed some minor clicks here and there. I’m on Windows though. I wasn’t sure if it’s from the system or the Axe-Fx III.
 
I know you said rebooting ax3 helps but just in case

Check your cables / try other cables if the same issue persists

Check your physical input and output connections for damages

Try another usb port on your computer aswell
 
All square here on my AF3 units, using a MacMini M4 Pro, 2013 MBP or 2020 MBP. FYI. Best of luck with resolving. Lee
 
I was having the same issue after that update. It turned out (I think) that running over 75% cpu was causing it to lose USB audio. Once I got that down to about 70% everything started working again.

Do you completely lose the audio until you reboot the unit or is it just some interruptions that get resolved by itself?

Exactly! I was trying to record and it went for maybe 5min then cut out. The only thing I could do to get it working again was reboot the Axe. I thought it was a USB issue but after some tips I reduced the CPU usage and everything started working again.

My main preset hovers around %55.0 and I was on it when this happened. So it's not related to CPU, it must be something else.
 
There have been no changes to the USB firmware (which is a separate processor) in quite some time. Our experience is that USB problems are either cable or computer related.
I've changed my USB cable and turned off USB selective suspend in Windows power settings. Will report if this happens again.
 
I've swapped the cable. Still dropouts. I've changed the USB input on the Mac. Still dropouts. The dropouts appear no matter which adapter I'm using. Fairly new computer. Strange...
 
In Windows you needed to go to the Device Manager and go to the the USB Hub it is connected to select Properties. Disable the allow windows to turn off USB to save power settingg. There be a similar setting in MacOS in System Settings.
 
Getting a quality powered USB hub has helped me, immensely. Still happens on occasion and also with no hub, too. Overall this happens to me maybe once or twice a month - and sometimes I leave everything powered on 24/7 so it’s just a minor inconvenience. Is there a technical explanation of how rebooting the Axe resolves a computer, hub or cable issue, as opposed to unplugging/replugging? I don’t claim to understand how USB functions. I use a MacBook Pro.
