I've found a bug. Collaborators on a Team Project in Premiere don't have sound from the proxies from footage that have 8 audio channels. Footage with 4 audio-channels, no problem.
Workflow : FullRes imported from server. Proxies (ProRes Proxy) are on a Shared Creative Cloud Folder. Attach Proxies. Then the project dans the folder are shared.
When I use footage from our FS7 that have 8 audio channels, there is no sound on the proxies for the collaborators within Premiere. They checked the proxies with QT and VLC and the files are good. Thave sound with 8 audio channels and all. The proxies have sound and works fine in Premiere on the owner's station. We don't have that problem with Footage with 4 audio channels.
I've never had any luck getting proxies to work properly with fs7 material with 8 audio channels. whether this is an issue with sony or adobe, I have no idea. However, the workaround is to "make offline" your clips in premiere from the camera original and "link" to the proxies. when you're ready to output, simply unlink the proxies and relink to the camera original. I recently had a conversation with an old friend out in LA who claims he. doesn't have this problem. do I believe him? not really. I spent a couple of weeks trying to create a proxy preset that would work. and never could.
