How to fix audio not playing with video error on Mac?

“I was having a movie marathon with my friends on my MacBook Pro 14 – everything was working fine till two movies. But after that, when I tried playing the third movie, strangely, I could only see the video, no audio.

I tried playing random audio files and YouTube videos to see whether this was a sound, hardware or media player issue. After checking, I was sure the video file was at fault, as all other videos were running smoothly and had sound.
