I have a Acer Asipre 774-6656 WIndows 8.1 64 bit notebook.
The audio output jack on left side does not work.
I hav edone the troubleshooting in windows for sound proeblem - no help.
I don't see a realtek sound card listed in device manager and I believe it is in the original specs fo rthis notebook.
I get sound fom the notebook speakers.
Have gone to control panel sounds and tried all the available adn even have disabled and disconnected devises noted to show.
I have tried a couple of speakers in the output jack tha twork on other notebooks - not the external speaker.
Any suggestions woudl be helpful.
I won't spend the money to replace the output jack - but would think this is a real long shot as the problem.
Thanks and Happy New Year.
