No Input in Ableton

Post by dave 13 » Mon Dec 29, 2025 4:31 pm

I am an experienced user but this happened Out of the blue, I plug my guitar in the Clarett 4Pre USB. Ableton is configured to receive the signal but nothing. It records a flatliner.

I made a test with Quicktime and now it recorded the guitar signal from Clarett. No problem.

In the focusrite control, I see the signal is coming in. But the output from the sofware playback has no signal.

I updated all the software to the latest version.

Does anybody has a clue?

btw how do i add a screenshot? when i do this, it only shows a link





macbook pro M1
Tahoe 26.2
Ableton 11.3.42
Clarett Focusrite 3.26

Solved: it was a permission thing in OS. The permission for the mic has to be turned on. Otherwise OS will not allow to record audio. Also from a soundcard apparently, which is different then a mic.
