I recently upgraded to an m4 series macbook and am using an older Universal Audio Apollo Twin Thunderbolt 2 interface with a hardware synth connected to it. When I monitor through the UA console it works fine but when I try to monitor through Ableton I get a quick "spike" in audio then it cuts out. I think the issue is some communication error between ableton and my old interface but I can't quite figure it out.

Here's what I’ve already tried:

• Buffer sizes from low to 512
• Running Ableton native and through Rosetta
• Blank project with zero plugins
• Turning off Reduced Latency When Monitoring
• Turning off Delay Compensation
• Matching sample rates everywhere
• Reinstalling/toggling audio settings
• Unlinking Apollo inputs and testing mono inputs
• Different monitoring/input configs

Important details:

• Apollo Twin Duo (older silver model)
• MacBook Pro M4 Max
• Ableton Live 12
• Monitoring through Console is 100% stable
• Problem ONLY happens when monitoring through Ableton
• Using a mixer feeding both Apollo inputs

At this point I’m wondering if this is some kind of Live 12 + older Apollo + Apple Silicon compatibility issue, especially with realtime monitored inputs.

Has anyone else experienced this or found a fix? I'd appreciate any help I can get! Thanks.
