When I plug my headphones I can hear from them and the computer’s speakers. What should I do to only hear from them?
in the properties u have turn off the front speakers
realtek hd audio driver dont have this option in the latest driver you have to manually lower the speaker volume
Open audio manager, on right top side there's "Device advanced settings". Click it and check if "Mute the read output device, when a front headphone plugged in" is selected.
Then click on "Connector settings", in my version (18.104.22.16894) it's the yellow button under the device advanced settings, and check that "Disable front panel jack detection" is not checked.
If it still doesn't work check if you have headphones connector on the speakers and use that instead, that should mute the speakers.
u can only do this..
turn off ur speaker aur plugged out them
aur disable form control panel
if you are not using speakers try to turn it off or mute the volume
Usually that doesnot happen..Check your connections and speaker settings on your control panel
You could mute the speakers in your audio control panel
Make sure your headphones are connected. Right-click the speaker icon in the notification area and select 'Playback devices'. Select the headphones entry and click on the Set Default button. Now whenever the headphones are plugged in, they should be the (only) device that the audio will be piped to. When you unplug them, it should revert to your previously selected default device (your speakers or HDMI output).
If you've tried this idea from Bruce and still have the same problem, so the other option would be to mute the speaker volume ;-)
If you are using a desktop like me then make sure your speakers are turned off when your headphones are plugged into them.
