Question about Computers & Internet
I have an Acer Aspire 7720z and have had the same problem. I am assuming your OS is Vista.
Go to Control Panel -open "Sounds" folder and you should see "Headphones" in the list under "Speakers". There will be a green tick on the "Speakers" symbol. Right click on the headphones symbol and then click "Set as Default device". Click OK and the headphone socket should now work correctly. It sorted my problem. If you want to go back to using the crappy internal speakers follow the same procedure setting the speakers as your default device.
