Audio monitoring BUG

Has anyone come across this? I have sent a report to Apple. I have tried this on 2 systems now with the same result.

This is for FCPX 10.2..

When I play/scrub a clip in the Event Browser and the clip's channel audio config is set to Stereo i hear the audio and see meter movement. I change the clip's config to Dual Mono, and there is no audio leaving the system BUT there is audio meter movement. I put it the clip in the Project (with Dual Mono config) and I can hear it.

Any suggestions?

Hey Simon,

Just tested this here, i don't have that problem. Tested on an iMac and a new MP. Maybe delete preferences could help? Always useful after any update.

Thanks Ronny..

I will try that right after I finish my export and I will post the result.

Not sure if it makes any difference but both of the computers that did it here are early 2009's MP's... either way... the prefs are first on the list of things to try.

Thanks again.

I have the same mono audio problem.
I delete preference and still have the problem.
I open a library that have a voiceover that was recorded with FCP X and all of them are mono and none of them playback from the event browser or in the channel configuration if they are set to mono, to be able to here the audio I have to set them to left channel or right channel.
If I add the audio to a project I can play back the audio without problem.

Hey Ricky,

What are your system specs?

Mac Pro (Early 2009)
2 x 2.93 GHz Quad-Core Intel Xeon
20 GB 1066 MHz DDR3 ECC
ATI Radeon HD 5870 1024 MB
AJA Kona LHi
2 x 8TB G-SPEED eS Pro RAID 5

Thanks!! So the common denominator for the issue so far seems to be the 2009 MacPro, which both of you use. If anyone else has this issue, please post here with your system specs.

Same here... didn't work after trashing prefs... here is my system specs...

Mac Pro (Early 2009)
2 x 2.26 GHz Quad-Core Intel Xeon

ATI Radeon HD 5870 1024 MB

Thank you, Simon. That's two early 2009 MacPros with the ATI 5870. Let's wait if we get any other reports to see if we have a pattern.

Same issue here on 2013 New style MP. Had to roll back to 10.1.4 as in the middle of a job... Didn't try trashing prefs - might try later and report back... Using ext UAD audio interface - that may be the issue? I notice FCP 10.2 switches to a mono audio meter when playing back dual mono clips now - where previously it seemed to play dual mono back in stereo until it was 'mixed' in the timeline... Perhaps this new mono 'output' isn't routing to the stereo interface for some reason?

Trashing prefs makes no difference. Seems to be a bug with FCP 10.2's new mono audio monitor not outputting to the stereo audio outputs... Weirdly - if I switch to HDMI audio on the system sound so that audio comes out of my monitor - it works fine... Unfortunately I need audio to come out of the audio interface to my monitor speakers. Typical - just as I was *finally* coming round to using (and liking) FCPX....

Simon, Ronny et al.

I too can confirm that this is a problem.

My specs:
Mac Pro Mid 2010 2 x 2.4 GHz Quad-Core Intel Xeon

Graphics ATI Radeon HD 5870 1024 MB

If I play a clip in browser set to dual mono, I get one audio meter and no sound. If I then set the audio to stereo, sound will play as expected and there is a L/R audio meter.

So the issue s that audio won't play when set to dual mono, but will if set to stereo. This is in the event browser only. Otherwise everything works when placed in Project

I also trashed prefs.

Is there sound on both channels? Same sound, different sound? Left or right?

No sound comes out of either channel and the audio meters now switch to mono, unless you make the clip stereo, then sound comes out fine

Tom and the gwyn.

Here is what I have. Again. This is only when a clip is selected in the browser/event.

Here there is no sound:



And here the audio works:

The single meter is the normal display for dual mono. I've gone through all the different types of file formats I have and can't reproduce the problem. It seems to be specific to a certain group of machines.

Tom,

If I recall correctly, and I just spent a good amount of time trying to work out my confusion with dual mono versus stereo:

Even if you set the audio to dual mono, there should (or I thought there should) be a two column meter.

Say I;ve recorded using a mixer using two mics in to different inputs. And then I pan one mic hard left and the other hard right. In then have sound left and right.

In FC if I converted that audio to dual mono, I would still see the two column meter as well as the two seperate channels if expanded in my project. I could then adjust either channel, left or right in dual mono to get the proper levels of audio from one or the other.

With the single column meter, it does not work that way. I think that with either Stereo or dual mono there should be a two column audio meter.

Maybe I'm losing my mind. :woohoo:

Here is what I have seen in the past:

Can confirm having gone back to 10.1.4 there's definitely a two channel stereo meter when looking at dual mono clips. The mono meter seems to be a new feature of 10.2 but it isn't sending sound to my interface

That's not what I see or have seen in the past. In the browser dual mono only shows a single meter. That's only in the browser. It shows two meters in the project. I even booted into Mavericks so I could go back to 10.1.1. It's always been like this in the browser since 10.1.

I am experiencing the same issue.

I haven't tested on my 2013 Mac Pro yet..

I see movement in the meters w timeline playback, as well after switching a GH4 Stereo clip (only right channel has audio) to Dual Mono, but it's like the sound level doesn't match the meter level- especially if you turn up the volume on the clip in the timeline. Inspector plays back fine..

The discussion on the meters being single or dual depends on the playback selected. Mine is two if in my Stereo timeline and one, if from the Browser, as expected.

* I tested this with the Apple stinger Space Log.caf as a control and receive the same results, -12DB in timeline meters, but the sound output doesn't seem relative.. report submitted, also.
