@RajalakshmiSund Hi there! Thanks for submitting this with the necessary context. I am sure it is frustrating. If students tap on the music note icon in the app (as shown in your screenshot), that should prompt the audio to play. Can you check that? Next steps are below after you have tried that.
If it does play, I would encourage you to have instructors put some instructions for playing the audio in the course to avoid more confusion. Something like this:
- Instructions: Listen to the audio below. If you are using the Canvas Mobile app, you must tap on the musical note at the center of the embedded player to play the audio.
If it doesn't work, then you likely need to submit a Canvas support ticket and provide our team with this context to see if they can get the issue resolved for you!
I hope this is helpful! Please let me know if you have any more questions.
