That error indicates an ASIO issue.
The first thing that I would look into is what has changed, since you last were able to edit perfectly. Did you install any software, or hardware?
Next, I'd get the very latest Realtek Audio driver and install it. Even simple OS updates can kill these quickly. Many players will have no issue, but an NLE works a lot more closely, with both Audio and Video drivers, and can encounter problems. Note: if you have a Creative, or other Audio board/chip, go to their site for the latest update
Then, I'd check the ASIO settings in Edit>Preferences>Audio Hardware. Here is my ASIO settings for PrE 4 on my laptop:
Last, if nothing else is working, look at ASIO4All. Install it (freeware) and then in Edit>Preferences>Audio Hardware>ASIO Settings, point to it for Input & Output. This has allowed many to get their Audio working with all sorts of equipment, when nothing else worked. It's saved many on the Audition forum days of troubleshooting.
PS - Welcome to the forum
Thank you very much for answering!!!
I found the solution of my probleme in anotrher tread:
"Try getting rid of the disabled files or just reenable them, then save the project under a new name, close Premiere, and then reopen it. "
Now it works!!!
But also thanks tothe_wine_snob. I learned much more about drivers and audios
If it should happen again, please note all the details to help troubleshoot the cause and prevent it from happening again.
Your reporting is appreciated. I now have another "trick" to add to the troubleshooting toolbox!
Good luck, and thank you,
