Adobe Premiere Pro Cannot Link Familiar File with 2/1 Audio Channels

Same issue here, can't believe this is still a problem. Adobe get the finger out!

Also having the same problem  This is a stupid problem and should be an easy fix for Adobe. Should require me relettering my drives to access proxies. 

Thanks for the help on this thread. Thought I'd share my solution.

I have been working with proxies remotely and do not have access to the source files. We recorded audio externally but I was having troble relinking the proxies to the source files. 

I offlined them all and jump in to the sequences and deleted all of the scratch audio from the camera (5 channels), that I no longer needed and just relinked the video to the proxy file. That left me with the externally recorded sound files (that I had tentacled synced previously) and the now linked proxies.

When it comes to onlining the source files, I'm hoping I don't face any issues... here's hoping

As a workaround, I offlined all the clips that had this 4 vs. 2 channel audio issue to get my project opened. Then filtering out the offlined footage out of my Dailies bin, I chose "Link Media", selected the missing clips and it resynced just fine.

I don't understand why Abode can't make this same functionality work simply by reopening an old project.

I just had a similar but slightly different project. I'm using Premiere Essentials though.

I was using the "replace footage" option since I had made some edits to a video file outside of Premiere and wanted to replace all of my clips in Premiere with the new version without taking an hour to do it manually. That error popped up because I was originally using a .wmv video file and was trying to swap with a .avi file. Silly mistake on my part, but replacing the original video with another .wmv file worked.

It probably won't work, but make a new copy of your video files with the same file extension of the original. Right click the video file in the Project Assets bin, chooose "replace footage," navigate to the new cop of the video file, and see if Premiere will load it. If that doesn't work, maybe use Adobe Media Encoder to convert the file to another format. I dunno, good luck.

How this is not fixed is baffling. What an absolute joke.

Same problem here.

I can't believe how basic this issues is and that Adobe has not fixed it yet.

What is the point of having proxies if you can't hand off a drive to editor or take your drive and edit on a different computer?

Adobe at its best. 

I had the same problem and I had the project on an external hard drive. The problem with relinking proxies was that premiere learnt the path of the project was on H: drive. After some days I opened it again, but with different letter drive (L:), and that was the problem even it was the same external hard drive! So the solution is just to change the letter of the hard drive to the original one (in my case it was H:). There are several tutorials on youtube how to do it.

Any more insights into this, as I have hundreds of clips like that?  I am in a major stress over this issue - I basically consolidated the project onto another hard drive that I need to give away for further editing, but now I keep getting the same message and have no clue how to relink the proxy media.  

I even tried to force relinking to the original, 4K media, but the same message appears.

I know this isnt a perfect answer, but if it's only 2 clips, can you manually re-import them (not relink, just important the current versions you have as though they were new clips) and then just manually swap out the two clips in the timeline?
