Help speaker sound stopped


Android Enthusiast
Hi there, looking for some help here. The speaker on my phone stopped working today mid song, does not give any sound now from speaker for anything. Have read loads of posts on this and have reset phone, pulled battery and SIM card but no luck. Downloaded an app called sound about it lets me redirect sound to the ear piece but speaker still not working. I am totally stumped. Any one got any ideas before I return phone for a repair which I do not fancy at this time of year. Thanks for any suggestions. Ear piece works during calls by the way.
