For the link, sorry, the editor said that I can’t paste links.
For previewing … well, when in Nautilus file manager, hitting space open the audio/video and other files in sushi plugin where for example opening the mp4,mkv, mp3,ogg etc. it opens the multimedia file in “preview” mode. Both video and audio worked, now it doesn’t for audio, only video for video files.
Example of that window:

The link doesn’t work as quote, and as a new user I can’t attach the file
