Speaker not working .no sound at all

@shauryaveer first you want to check if your speaker works in Safe Mode. If it does, then the issue is related to a 3rd party app that is interfering with your speakers function. You will have to delete those 3rd party apps. Use this video to learn how to place your phone in safe mode.

If it does not work in Safe Mode either, consider replacing the speaker. Since iFixit does not yet have a specific guide for this, use the one from here It is written in Spanish so use a browser that will do the translation for you. Replacement speakers are readily available at many online stores.

While you work on your phone, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has a device with the same issues as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
