When i plug-in my HeadPhone/Speaker and play any music there is no sound.
when i plug-in my Headphone/Speaker into the audio jeck it detects the the device but no sound coming from the pc.
I have reinstall the driver but the problem remains the same.
Before we can give a meaningful advise, please tell us what have you done to try to troubleshoot the problem. For example, are you sure the volume is on high & not mute? Is the speaker/headset proven working? etc...
