Hi. I exported a project with some hard-panned elements in the audio track, but the exported video plays back audio in mono (and with the panned sounds quieter than they were in stereo). It plays back fine inside Premiere, but the exported file has the mono problem. I didn't notice it until I uploaded it to Youtube. I thought maybe it was a Youtube issue, but I tried playing the file in various video players I have and the problem crops up in each one.
