no the header was clear; Exported video renders at 100% done no completion sound, hope that was clear enough, sorry if I did not express it in detail. this has been this way since PD3

Are you asking for a way to export a video project as an audio-only file?

Just select the Audio tab on the Export page to choose an audio format you prefer.

If you are referring to an issue, check if you've muted the audio track on timeline and check if audio works normally at the preview playback moment before you exports the project.
