The old gif format doesn’t support audio. Anything called gif with audio are mp4 video files. On the imgur site, you may have seen files with the extension gifv, but…
Quote : “When you view a GIFV file on a website such as Imgur, you’re viewing a video file, which would normally have the file extension .mp4 or .webm. The server is configured to serve the video using the extension “.gifv,” but the video’s file format is unchanged.”
