Host: AUHAL vs CoreAudio?

[Chris115v]

I'm on a mac (macOS 15.5) Seeing the Host: drop down in my Check Level dialog does not look familiar. I see it in the online help for other systems though. What is "AUHAL" and how does that differ from CoreAudio? Is one preferable?

Hi,

One customer was having some issues with recording, so we added an extra option to see if it would resolve it.

AUHAL is how the software was working previously.  We added Core Audio, which is a different (older) way to talk to the audio hardware.

Apple recommend AUHAL and so do we.
