Yes, Nvidia is selected. There is no Intel integrated, since this is an AMD CPU. And yes, I tried with hardware acceleration both on and off. No difference at all.Ken Berry wrote: ↑Sat Apr 15, 2023 7:39 pm Did you look in the NVidia control panel to see which GPU was being used: the Intel integrated one or your NVidia one. Setting hardware acceleration to AMD would achieve nothing positive since you don't have an AMD GPU. Your AMD hardware is a CPU not GPU. So it is a choice between Intel and NVidia, and you'll only know which one is being used if you look at the NVidia control panel as I described...
The other things you could try are once you have moved to render the project: try turning off or on Smart Render and Hardware Acceleration there. This may make the render rather longer, but it would be interesting to see if it eradicated your problems with the audio chopping and changing.
Telling it to create the proxy files each time I open the project and then clicking on the affected clips and choosing "Reset Volume" is the only thing that provides a temporary solution. The problem keeps manifesting itself in different ways. In one section, I had an overlay track muted and it also didn't play the sound on the video track and in another section the sound of the video track got distorted and severely amplified to the point that it hurt my ear.
