The 27-year-old singer, dressed in a floor-length red gown, took the stage to perform her song 'All I Ask' from her album 25 but there seemed a glitch in the sound.
While the fans praised Adele's performance, they put the blame on sound problems.
"Some sound guy's getting fired," tweeted an user.
"All of the sound guys in the building better be fired immediately. #adele #Grammys2016," said another.
"The sound guy just messed up the sound during Adele's performance so everyone get your damn pitchforks," a fan wrote.
"How dare they mess with the sound while Adele is singing. How dare they," said a devoted fan.
