I second the comment below, 'Need to be able to make custom proxies and have audio 'same as source' to avoid this issue.'

Almost 2023 and this mess still hasn't been fixed. I still get relink errors when changing drives, EVEN when generating all proxies in premiere using the ingest system.

Need to be able to make custom proxies and have audio 'same as source' to avoid this issue.

Shot High Frame Rate footage, which by default has no audio, and get this annoying error. Shooting Canon Raw CRM files, the Canon c500 generates proxies on camera and can't effin use them... so annoying having to render hundreds of proxy files for all that footage I already have....

This is not a permanent solution but a work around that seems to be working for now.
When you create the proxies make sure your proxy preset has the same channel layout as the original file. Mine come with 4 mono tracks so I made sure to include that in my preset.
Next create the proxies and go into media encoder to ensure it is all working correctly. I have had many issues with it changing my preset to an ingest preset and not adding my custom watermarks etc. Those can be fixed by resetting the proxies in media encoder and ensuring the correct preset and save location are specified.
Also, before hitting start on media encoder make sure to go back to the clips inside Premiere Pro and ensure that the Audio Channels didn't change while creating the proxies. For some reason when I create proxies it automatically changes the Audio Channels from mono to adaptive and this messes with the matching audio channels.
Most of the time when the proxies are finished it all works and the channels are correct. Sometimes, they are not, especially the first clip that starts before I get a chance to fix the original audio channels. In this case detach the proxies and make sure those Audio Channels are correct, then go ahead and reattach them and everything should work fine. Now I can go in and edit the Audio Channels to my liking.

This is no fix and a serious pain and waste of time to my workflow but for now it will have to do. As I've done this with 1000's of clips it has become easy but does add minutes to a workflow that should take seconds.

I can absolutely confirm that this is possible to achieve via ffmpeg. We are using Iconik as a MAM and the edit proxies automatically generated all have matching audio channels.

This should be one click easy peasy. We don't want to use Avid, but these kinds of things are so easy in that world. We shouldn't be constrained by these needless hurdles.

This should be so simple. Just let us make proxies!

This is really killing us, please help.
Thank you.

Proxies are supposed to save time, not add extra steps to make them work correctly.

Actually is unbelievable that we have to ask for proxie have matching audio channels. C'mon Adobe

Another vote: Please allow for proxies with single audio track to replace multi-track audio. If not it really renders the internal proxy-generation abilities of cameras useless in simplifying post workflow.

Please make this happen - this feels like an essential function for an app of Premieres caliber

I vote for this and I am very frustrated that Adobe continues to sit on their thumbs rather than take action to make this update. I'm personally getting sick of shelling out money to Adobe for reasons like this.

Having an integration with poly wav split audio would be helpful. But that's been here before, reiterating.

When creating proxies using the Quicktime ProRes Proxy settings for clips that I've purposely set to mono, Premiere always changes the first clip in the batch to adaptive. I have to detach the proxy for that clip, reset it to mono, and then re-attach the proxy. I imagine there's lots of people out there who use adaptive clips, but I for one have never found that setting useful. They seem to wreak havoc with proxies; proxy audio channels do not seem to match master clip audio channels when the adaptive settings are used.

Please change this. It's a fault that cuts to the fundamental failure of Premiere not to give the user ultimate control over everything and that is where Avid and increasingly Resolve gives Premiere such a good spanking. In Avid the user can select or deselect everything - there is always a fix or work around. The issue that Avid then has to deal with is fiendish complexity, which Premiere doesn't have. It would be fantastic to have a straightforward system where everything can be changed...!!! In Premiere you always hit these seemingly pointless brick walls. Now I have to reconfigure all the proxies I created in Media encoder.... my issue is that Canon MXF seem to have 4 numbered audio channels that I can't delete and yet I created two channel proxies with left and right, the modify audio channel box simply doesn't have enough buttons to change more things about the representation of the media and there is lots of space for more buttons...! My overall suggestions would be more more functionality but not at the expense of logic - more complex yes, but more complex logically, there is so much in Avid which seems like the Ivy grew round the house and became knotted and illogical, and operates against itself, if we could have much more functionality that works in a straight line, where its expected to be and not in conflict with another function that would be great...it seems crazy there is still so much that is imperfect about all these editing systems in 2021, why aren't they perfect by now? Why have they become less perfect over time, I think that is a fundamental question that needs answering.

Not only this, but they need to allow us to use audio passthrough for building proxies.

Oh my gosh, this is doing my head in! Handed over a production with 38TB of footage , proxy files generated outside of adobe with 2 channel stereo audio vs the Full-Size version which have 5 channel mono and now can't connect the Full-SIze media short of Offline/Unlink the whole sequence and then link manually. If I use auto-connect other media it only re-links the one file and the rest connected back to the low res versions. I'm sure there is a work around but a what a mission... Please give us the option to choose whether or not we want the audio..

I use Adobe Premiere to make proxies, and it's always worked fine, but after a recent update it longer works for me. The issue is the audio channels.

My camera (C300 mkiii) records 4 mono channels. I have to use ProRes to make the proxies since h264 doesn't support 4 channels. The audio on the proxy does not show up on my timeline, but it does when I toggle the proxy off. It never used to do this, perhaps a recent update changed something?

This is utterly frustrating, has there been a fix yet?
