Seperate audio file not working when importing a video file

[jahaniam]

Describe the bug
The sound from source doesnt work. I have a video and an audio that I want to play in a loop. The source files are different files.

To Reproduce
Steps to reproduce the behavior:

1. select loop and upload a video
2. For audio do not select the video source and select loop again to upload an audio file.
   You will see that the video will be played and audio does not play with it.

Expected behavior
The video should loop through video source and audio should loop through audio source.

I used the latest and dev container both have the same issue. I appreciate any help on this.

Please make sure that you encode the audio to AAC in case your audio loop source is a MP3 file. Some browsers will play the audio if it's not AAC.
