I get audio pops quite a lot but in my case I don’t think it’s a sample rate thing.
My footage is digitized at 48k and my audio project is set to 48k.
Sometimes I can view the audio tracks sample plot and see a little tick mark where the pop is,
other times there is no mark on the timeline. If the pop is on an imported clip sometimes I just re-import the same file and the pop is gone. I also get a lot of corrupt audio dissolve renders, but it only seems to happen when the dissolve is 5 seconds or longer.
Pretty frustrating.
