In my opinion, based on what happened a few years ago:
Use this uninstall tool, from step 6:
And reinstall the program as administrator.
And in the future, you will not use registry cleanup tools like any other means that indicate you have invalid registry keys linked to Premiere.
You will see if it fits your case.
Maybe go into PPro preferences for audio stuff... see what you got. PPro WDM or MME or whatever , also other settings...change them and see if that fixes it.
Are the GH4R files in a .mov wrapper?
Something like 2i is working. But the situation is really bizarre, and I cannot tolerate it. I cannot work like this. Adobe really needs needs to get its act together because these random issues are extremely frustrating.
When I create a project on a different disk than the disk with all my clips it all works fine. I move this working project file to the same disk, it nicely locates the media, but there is no sound! When I move it back to the other disk is works again.
Is there a way to get rid of this ridiculous behaviour? It all worked fine with the previous version of Premiere Pro, and this total breaks my folder structure.
It's very frustrating when things don't work out the way expected. But there are tons of variables. For example, are these disks external and is one formatted FAT32 and the other formatted NTFS ? We don't know much more about what you are dealing with than you do.
It is frustrating but at least you have something that is currently, like, working ?? hehe, thank God for that !
It is even more messed up, but perhaps there is something interesting that might help pinpointing the issue. I used to have my projects and media files in one place earlier: I created a new folder in D:\Temp for each active project. This is a fast disk, and it was faster to edit this way. Then I moved off each project to a more "permanent" location when it was fully edited and done. I have changed the underlying storage in my "permanent" location, and it is quite fast. I was hoping to have everything on one place from the start.
But somehow Premiere Pro is "stuck" in my old D:\Temp sub-folders. If the project and media files are there everything works file. When I move anything to the "permanent" location then something breaks with the sound tracks: either no sound, or no wave forms or both.
Everything is NTFS, the D:\Temp is an Intel Matrix Storage RAID5 with SSDs, and the permanent location is a MegaRAID RAID6 with 6 mechanical hard drives.
Where's the Cache?
Media cache is in its default place C:\Users\...\AppData\Roaming\Adobe\Common\
Scratch disks point all to C:\Temp\PremierePro\
OK, I don't know that this is the issue, but my first thought is to recommend a new setup.
