head phones not working when plugged into front panel head phone jack

Thank you for your message.

Have you tried using another know good earphone on the front audio port to check if that works fine?

Do you get any popup message when you connect other headphones to the front audio port?

What is the system model?

Open device manager – expand sound & video – right click on the audio driver & click on uninstall (do not check the box that says delete driver) restart the computer. This will refresh the audio driver.

For better assistance, please click on my Dell username & send a private message with the service tag, registered name & email address.

Thank you Sreejith, this is a Dell OptiPlex 7020. Windows 7 64b. In Device Manager I see two devices. One is a "High Definition Audio Device" and the other is a "Intel(R) Display Audio"  Not sure if one of these was created when I plugged in a Philips Microphone for Speech Recognition software I was testing or not. But do you think I should delete one of these before I proceed w your recommendation? And yes I have tried other headphones in the front port wo a response from the PC.  Thank you again

Optiplexes for over 15 years now disable the front audio when speakers are plugged in the rear.

Thats why sound bars have headphone jacks on the side.  You cant operate both simultaneously.

Hmm, I tried it on another OptiPlex 7020 w speakers plugged in and I received a response (pop-up) asking if I wanted to use the Speakers or the headphone. That is my issue, I am not getting a response from the input of the headphones from my  OptiPlex 7020  Not trying to operate both simultaneously-but I should be receiving a response asking me which do I currently want to use-the speakers or the headphones I just plugged in...

When the generic driver for audio is installed it will not 'detect" things plugged in.

This is true for Realtek as well as for soundmax.
