What system, brand/model? What operating system? No sound through speakers or headphones or both? Are you certain the volume slider is turned up?

my system is acer.the operating system is windows xp.my speaker and headphone can’t take the sound…all are in good condition :kiss::frowning:

Welcome to the forum radhakrishnankv :slight_smile:

Did you make any changes that may have brought this about? Try checking the master volume, either that little speaker icon on the bottom right or go into the device manager and go into the one that says sounds (then click advanced). You may have one of your levels either muted or very low.
