Hi Venkatesh!
Sorry to hear you've run into this setback! Happy to help!
I tested the behavior on my end in the current version of Storyline 360. After publishing to Review 360, as well as LMS, testing with SCORM Cloud, I was unable to reproduce the same issue. Whenever I clicked away from the course window, into a new tab, the audio and video stopped playing.
Do you mind sharing which browsers were used when you encountered this issue? Also, it would be helpful to see your .story file and test it on our side. Feel free to share a copy here in the discussion or privately through a support case.
Looking forward to hearing from you!
