When play a music or video, the sound comes from biased one speaker. What should I do?

Galaxy devices supports Hearing enhancements function and, you can hear biased sound except for calls when Left/right sound balance as one of Hearing enhancements features is enabled. If the control bar for adjusting the left/right balance of sound is set by moving it to the left or right end, media sound will come out of only one speaker.

Please adjust control bar for proper sound on following paths

* Path : Settings > Accessibility > Hearing enhancements > Left/right sound balance
