S7-191 Headphone Jack not Working

lingyuan-he — Fri, 27 Jun 2014 19:48:45 GMT

I am using an Acer S7-191 with Windows 8.1, I had the system reinstalled with Windows 8 and updated to 8.1 after an windows update crashed the original system.

The problem is I cannot plug headphone to playback. In playback devices, there are only Speaker and Digital Audio HDMI even after I chose to display all disconnected and disabled device.

Here are what I have tried:

Install all recommended driver on Acer's webste
Install all Windows updates
Install and reinstall Realtek software and driver on Acer's website (6.0.1.7027 W81 64)
Update driver in device manager
Disable front panel jack detection in Realtek software provided by Acer (after that no "2nd Output" tab appeared)
Check if there is any device unrecognized or with warning mark, none found
Change a headphone to try the connector
Use Realtek official universal software instead of Acer's

I am running out of solutions, anything else I can try before I have to send the unit back?

In device manager:

Thanks.

I do apologize to say but it sounds like you have gone through all the troubleshooting I could recommend witout having the system sent in for repair. If the jack is not working when you connect your headphones and they do not show up in the Playback tab, then I would recommend contacting technical support in your region for repair options.
