Hello, we installed Windows 7 Professional on our Optiplex 9020s. Whenever a user inputs a headphone, into the front Headphone jack, the audio works fine (it will only play from the headphones and not the internal speaker - as it should). When we unplug the headphones from the jack, the internal speaker plays the audio then. Is there a way to permanently disable the internal speaker without cutting/disconnect it from the Motherboard?
I've tried the following:
Disabling the device (found in Control Panel > Sound) - This also makes the headphone input disabled.
Any other suggestions would be helpful. Thanks in advance
The easiest way to resolve this is to simply remove the speaker. Select your correct form factor from the list of manuals below and then look for the section titled "Removing the Speaker."
Tested this just now with successful result
