I'm using Premire Pro version 23.2.0. I'm on a custom built PC with a Ryzen 7 3700X 8-Core Processor, a GTX 1660 Super graphics card, and 32GB of RAM. I'm editing .MXF files from a Sony FX6 shot in 4k60fps on a 24fps timeline, along with .MP4 files from a Sony a7iii shot 1080p60fps, in the same timeline. I have my paused and playback resolutionsset to the lowest they can be (1/4 in program monitor and 1/8 in source monitor).
My audio is constantly dropping out, to the point where I can barely edit because I have no reference the sounds. It'll be fine for a few seconds then just goes mute. I pause, wait a second, only to play and get the same result. Sometimes I'll play it again to only get video playback, no audio. Even when rendering everything it will still drop out (I render effects, then render in to out, then render audio. I know thats incredibly redundant and unnecessary, but I thought maybe that would help. It didnt). Video will drop frames as well sometimes, but the audio cuts completely, on all tracks. I cleared my media cache through preferences - no difference. I changed my project settings from memory playback engine GPU acceleration (CUDA) to Software Only - no change. I don't know what to do. I feel like my system is powerful enough, but I could be wrong. I thought maybe 4k60 MXF files could just simply be too big and thus makes the playback suffer, but it happens even with 1080 mp4s. I'm at a loss. I've attached a screen recording of the audio cutting out. It didnt record the actual audio unfortuntely, I can't find a program right now to do that quickly but take a look at the audio meter on the right hand side.
