Controller mode: no Input

[fourstones]

12.4.2 (Build: 2026-06-04_a687113d71)
P3 is 'up to date' with latest as of today

Connect P3 to Live
Create Audio track
Plug guitar into Input 1 in P3
Set Preamp Type to High (or Inst.)
No input is registered in the meters

Notes:
- Macbook M1 Pro 2021 / Tahoe 26.3.1 (a)
- I can input guitar in standalone P3 mode no problem
- Live->Settings->Audio->Output/Input Device sees the P3 and output audio just fine
- I have jiggled all the knobs in P3->Settings->Audio
- I have rebooted both boxes (p3 and laptop)
- If I then switch to Standalone mode, I get no audio in or out, I have to reboot the P3

Is Push set up as your input soundcard in Live's Preferences?

Is Push set up as your input soundcard in Live's Preferences?

In the latest version of the software it's called 'Settings' and yes, it is both set as input and output and the output works just fine.

Just to be clear: the meters on the P3 register no input.

You're right, I think i'm getting too old! That being said I stopped saying "apple" instead of "cmd" a few years ago, so I'm confident I can evolve and adapt

Back to your topic: are you seeing the same issue with the 2nd input?

[fourstones]

are you seeing the same issue with the 2nd input?

yup.

the exact same inputs and rig works fine in standalone mode.

Hmm...
Try to reset Live.

If that doesn't help, you could try re-installing Push's previous verison, you can find it here in the download archive.

BTW, i thought you said the issue appeared after updating, but it doesn't seem to be the case.
Any idea when it appeared?

Any idea when it appeared?

The unit is 2 weeks old - I updated the software as soon as I booted it up the first time. The audio input for controller mode audio interface has never worked for me.

Redoing the preferences on the laptop did not make a difference. I'm not inclined to backtrack on the Push software until I've exhausted everything else - I'm assuming it's easy to restore the latest version from within the Settings->Software page on the P3 if that doesn't pan out.

Yes, you don't have to worry about this.

If you prefer you could first try installing an older L12 version and see what you get.

Same behavior with previous build.

We can rule out hardware issue since it's working fine in standalone.
Sounds stupid but, are you using the provided usb-c cable?

If that's not it, then it's definitely something on the software side. Is that your macOS, or is that Live. If that needs to be tested, you'd need to uninstall every Live-related system files (no need to delete you User Library and Projects) and re-install it. I know you tried installing an earlier version, but if a Push-related corrupted file is being shared/used by Live, no matter which version, then a clean re-install is needed.

But, that could also be a software issue on your Push; so you might have to also revert it back to a previous version, or reset it.
Once the usb cable is out of the equation, I would probably go with the Push reset first.

- I copied all my projects and user settings from Push onto my laptop
- I deleted Live 12 from my laptop
- I moved/renamed the Library/Preferences/Ableton folder
- I reinstalled Live 12
- I reset the Push3
- re-authorized everything

Still have the same problem - no input seen on the Push3 in controller mode

Is that the cloth braided one?

[[jur]]

Nope.
It has rectangular connectors, and ferrite blocks.

rectangular connectors, and ferrite blocks.

no change

- I deleted Live 12 from my laptop

Before re-installing, did you remove what's in macintosh HD > User > Library > Application Support > Ableton Live
and macintosh HD > User > Library > Preferences > Ableton ?

If after doing all this you're still seeing the same issue I'm afraid I'm out of ideas. You'd need to reach out to Support.
