5.1 Mixing - Center Channel Broken with new update

[kevinh4466535]

After updating, none of my center channel audio is writing sound to the 5.1 mix.  If I take center from 100% to 0 it works but when set to 100% center, I get nothing in the 5.1 mix.  I have been using the same sequence presets that I made for a year now and now they are all broken.

[Moderator note: moved to Bugs section of the forum, as that will flag this for the developers.]

Is it just a monitoring issue or are the exports faulty too?

[kevinh4466535]

I haven't tried an export yet since the update.  As far as I know it's a monitoring issue...  I have levels on the audio track mixer, it just isn't writing to the 5.1 submix.  I'll keep you posted about the exporting.

[kevinh4466535]

Just tested.  Exports are faulty.

[Richard M Knight]

Could you post some screenshots of the track mixer and your ausio hardware settings.

[kevinh4466535]

A6 (VO 1) has the center channel set to 100%, it should be coming through on channels 3&4 on the 5.1 submix

[kevinh4466535]

I mean channel 3.  4 is LFE.

[kevinh4466535]

It appears there is no LFE coming through on the 5.1 mix anymore either.

Hi Richard,

Just checking in to see if you've heard anything else about this issue.  Thanks!

[Richard M Knight]

I see that your vo track is stereo. There is a chance that the stereo track is out of phase, try adding the fill left with right effect to the track.

[kevinh4466535]

That didn't effect it.  I've started a new project, same problem.

[kevinh4466535]

It appears more than one person is having this issue now: https://community.adobe.com/t5/premiere-pro-bugs/no-audio-from-center-channel-in-5-1-sequence-in-pre...

[Evan245242147pw8]

Exports were faulty for me as well.

[Evan245242147pw8]

I was using multiple fill left with right and fill right with left effects on various channels, but the issue was still present.

[Evan245242147pw8]

I am also experiencing this same issue today. Projects I have previously created in 5.1 will no longer allow me to monitor or export channels 3 or 4, the center or LFE. The Audio Track meters still show levels during playback.

I moved the project to a different computer which had not updated to Premiere 23.1, and it worked as it should on the older version.

[kevinh4466535]

I also reverted back to 23.1 for premiere and media encoder.  Issue is not present in these versions.

Same here today.  I rolled back to 22.6.3 and everything worked as expected.

When mixing stereo to 5.1 then the both center and subwoofer are silent once maximized (the Mix output is silent):

Though sub-mixing stereo to mono submix with center setting works:

So only stereo to 5.1 center and subwoofer are broken. Mono to 5.1 still works as designed.

Same problem here.

While all other settings are not giving me any problems the 5.1 Center and LFE are dead.

Did anyone get any news on the fixes from Adobe?

[kevinh4466535]

Only option seems to be to revert back to a previous version as of now, unfortunately.  I guess another option is to mix from mono as krasoft pointed out.

[Sergio-CS]

I think I found a workaround until Adobe fixes the problem.

I have a full show that I'm editing for VOD (Netflix, Hulu, Amazon Prime...) right when I was about to deliver...the [center] and [LFE], went dead.

In full panic mode I exported all the stems as single mono (so stereo would be 2 mono tracks) and imported the entire show in Audition and now remapping and exporting as 5.1DD.

I'm in the process of completing this task, but (so far and knock on wood) it seems to work.

I'll be submitting the new file with a 5.1 separate audio track.

It's not the best solution, but I hope it sparks some ideas.

Hi All,

Matt from the Adobe Audio team here.

Thanks for reporting this.  It is a bug that is already fixed in the Beta, and should be fixed in the net version of Premiere.

[rickg1949]

Matt, 

When will that update be available?

Rick

You can easily install the beta alongside the regular version. Quite frequently, you can work projects in the beta without issue. And if there isn't, the project still works fine in the shipping version after trying it in the beta.
