HTC One - speaker issue

HTC ONE

Hi Guys, Kinsa naka try ani.

I notice today that my BOTTOM SPEAKER side is not working.

I also tried the HTC diagnostics *#*#3424#*#* - it really indicates that the bottom speaker doesnt produce any sound.

Top - Left channel Speaker
Bottom - Right Speaker

I have used an app from play store called Stereo Test, the test is working fine with headphones attached to phone. But testing the Right builin Speaker doesn't produce anything at all.. Phone calls are fine.

I notice a day before, i hear a little pop or crackling sounds coming from the speakers, but I dont think it can be much to destroy the speakers.

I already cleaned the speaker grills to make sure its not dusts covering. I can also confirmed that the bottom (right channel) speaker really doesnt produce sounds - doesnt produce any vibration on that area.

Any ideas guys?
