Phasing/doubling the sound with the cue outputs

[olgalala]

The sound is like doubled, phasing effect, when I send it to my cue outputs. Empty session, the playback engine is set to my sound card, 64 sample buffer, no insert plugins, just a direct bus to my cue output.
Same thing in LML.
Of course, no direct sending via the UAD Console and no monitoring problem in Console.
I don't understand where the problem could come from.
Is there a setting in the preferences that could cause this?

Mac studio M2 Max
Sonoma 14.5
Pro Tools studio 2024.10.2
3x UAD Apollo X8p
1x UAD Apollo Twin

What is LML you mean LLM? Low Latency Monitoring?

---

Is this only on monitoring or the phasey sound is also recorded to the audio track?

What inputs are you using on the Apollo?

If it's input 1 and maybe 2 then make sure that when Pro Tools has focus (i.e. is the top most window on the desktop) that the Mic mode is 'standard' not 'voice isolation'... under the orange Mic icon in the macOS Menu Bar, make sure the Pro Tools icon is showing there as well so you are looking at the setting for Pro tools. Actually check it regardless of what inputs you are using. No this does not just mean for the Mac microphone it affects some of the low number ports on all interfaces used by all CoreAudio apps (like Pro Tools). It is an *incredibly* badly implemented feature,... thanks Apple.

If that is not it...

Check for hidden tracks that are not disabled, very easy mistake to have happen.

Esp. check for plugins on master faders that might be hidden.

Beyond that the likely cause is of course something going on with the Console.

Check again super carefully where DAW returns and inputs are going in console. If nothing else try totally resetting the Console. Just do it in case it's messed up an lying to you.

In Pro Tools it might take a corrupt session. You can try creating a new session (not from a template--that may be corrupted), try defaulting all I/O inputs, outputs and importantly bus pages and make sure sure paths there are labeled correctly and going to where you expect. (mistakes there might compound with the Console doing stuff).

Thanks for your reply.
Yes, LLM.
The phasey is only on monitoring.
It's not the Mac Voice isolation.
I test on a new completely empty session...
PT Cue outputs go directly to Cues in the UAD.
Cues work fine in Console.

So... try resetting the Console, doublecheck stuff very carefully. Try trashing prefs.

What does the exact signal routing look like in your simple test session? Share your test session online. Or post clear screenshots on a file or photo sharing website and put the links here. (don't post images directly on DUC, they get downsampled to the point of being useless).

If you hear the same effect with monitored inputs with LLM enabled then I would expect you are using a send somewhere and have enable sends during LLM enabled. (Trashing Prefs will disable that). Otherwise LLM should mute all monitoring paths.

I have same problem since Pro Tools studio 2024.10.
When I back to 2024.6 everything is ok.
Try to install 2024.6

[olgalala]

Thank you both for your feedback.
After uninstalling console and PT, then reinstalling PT 2024.6, the problem persists.
But I found the culprit, it's SoundSource. It causes latency.
I excluded PT from SoundSource and everything is fine.
I thought SoundSource only acted on the main output...
