Thanks, that worked. Previously I was doing an uninstall and then an install but was not solving the problem.

Thanks, I've just exported a clip to .wmv and the sound comes through fine, I'll do an MP4 now. Here it is, I've included an exported mp4 with no audio. https://drive.google.com/drive/folders/1UdbOsJcDU2_jmtUpa7EevvaO6yL-d6xX?usp=sharing The original video is silent (intentionally) until about 1 min. Also I realise that I may have never exported to MP4 before so I may have had the problem all along. I've just started recording mp4 from a Blackmagic Atem Streaming Switcher.

Preset HD 1080p File Format .mp4 Resolution: 1920 x 1080 -1080p HD Widescreen fit: Letterbox Frame Rate: Variable Frame Rate (Max 29.970fps) (Video was originally recorded at 30fps) Subtitle: Overlay Estimated File Size: 2.21GB Hi I did upload my file, but the ftp process wasn't exactly transparent so I've no idea whether it uploaded. I'll get a google drive link as you suggest.
