Xperia arc S speakers having noise

[ymonga05]

hi, I am using Xperia Arc S and the speakers have noise and the sound quality is poor. The sound is flat and has not bass or beats. Kindly suggest.

check the speakers by dialing *#*#7378423#*#* and selecting service test.

if you think speakers are not working properly take the phone to the nearest service center and get it checked,
