Check your volume settings on phone. -Go to the main menu on the phone , go to settings, click on sound icon, and check volumes settings for music, videos, games, ringtones, alarms and other media. You can check the speaker and see if there is a problem with the speaker physically visible -Check and see where your speaker is located and check if its free from dust or anything obstructing it. you can replace the Speaker -Follow this guide (Blu Studio 5.5 S Speaker Replacement)
