Offline audio channels in timeline but not in bin

[Jon Coyopa]

I have a clip in my timeline with 4 tracks of audio.  I noticed that there are waveforms for only one channel.  I checked the channels and saw that only channel 1 was selected.  I fixed the channels so that they are mapped correctly but the the waveforms didn't change.  I match framed to the source monitor and noticed that channels 2-4 are offline.  I checked the bin and the chanels are offline there as well.  This is a proxy so I, detached and reattached the proxy.  The clip in the bin now has all channels and they are mapped correctly. However, when I take the clip to the timeline the same issue happens - no waveforms on channels 2-4 and when I match frame, the same chanels are offline.  I made a new sequence and dropped the clip in there and  everything is fine.  I made another new sequence and pasted my cut in there and when I drop this clip in, no waveforms on channels 2-4 and they're offline in the source window.  

I know the audio channels on the proxies and raw match (I learned that mistake the hard way).  I am hesitant to delete the cache since this is a HUGE project and rebuilding that will take forever.

Any ideas as to why this is happening?  If I'm forgetting anything, I'll try to answer ASAP.

Are you working within a Production? If so, try adding the clip to a sequence that's located in the same project as the original media and see if that makes a difference.

Yes, we're working in a production and by placing the clip in a sequence from the project where it lives showed the correct audio channels.  So, as a test, I pasted my cut into the same sequence and the offending clip now shows wavewforms on all channels and they are online when I match frame.  Any idea why this is happening?

It sounds like that project hasn't updated the status of the proxies. I would suggest moving its sequences to your media project, deleting the old project, then moving those sequences to a new project.

Thanks, Paul.  That's what I did and everything looks good now.  Thanks for your help.

Any idea what would cause the project to not update the proxy status?
