G780 win 8.1 left side of headphones not working

Hello good people of Lenovo Community,

 

After having been trying for quite a lot of time on my own, I'd now like to ask you for any suggestions regarding the following problem: My earphones don't work properly, however only when plugged into my G780 laptop. Actually if I put the jack fully in, only right earphone works, while the left is dead; if I put in it let's say up to 50% then only left earphone works, and the right is almost dead. I've tried it with different headphones and got the same result everytime. When I use my earphones on other devices (mp3 player, cellphone, etc.) they seem to be working just fine, no malfunction. This occurs no matter which source is being used to produce sound (youtube, bsplayer, windows media player etc.). 

 

I've updated the Realtek Audio Driver - perhaps not 100% correctly - however when I open the device manager and check for update of the sound card driver it says it's already up to date.

 

What else should I try? Oh, as I said my pc is G780, Win 8.1 64 bit, i7 Core etc. 

 

If anyone could help me I'd be truly grateful,
Pete

Hi Pssecho,

 

Welcome to Lenovo Community Forums!

 

I’m sorry to hear that the Headphone is not working as expected when plugged into your G780 Laptop, please let me know if the headphone that you are trying to connect is a headphone without any Microphone and let me know if any other headphone is working as expected in the computer.

 

Hope to hear back soon

 

Best Regards

Shiva Kumar

Re: G780 win 8.1 left side of headphones not working

Hi Shiva,

Thank you for accepting me to the community!

So, my headphones have no microphone, just the 'speakers' part. As I mentioned, even when I try with a different set of headphones, the problem remains the same. On top of it: when I plug my headphones into another device, they work completely normally - as expected!

My wild guess is that it's related to either sound card, drivers or both, however I have no idea how to fix the problem.

Thank you for your help.

Kind regards,
Pete

Hi Pete,

 

Thank you for providing the findings, please check the issue in Sound Properties as informed by “Abdul_Ahad” in the above reply, if the issue persists even after that please re-install the audio driver by downloading a fresh copy of driver from our Support Website and while installing the driver right click on the downloaded file and select “Run as administrator” option to get it installed without any error.

 

If the issue persists again please perform “System Restore” in the computer to confirm the issue, below is the link for the steps to perform “System Restore” in the computer.

 

Do post us back if the issue still persists.

 

Best Regards

Shiva Kumar

Re: G780 win 8.1 left side of headphones not working

So, first to reply to Abdul_Ahad,

 

Thank you for you suggestion. It indeed looks like the balance has something to do with the problem, however I did think of that already and have checked it couple of times before writing to you guys; I checked in Windows as well as in other programs which were being used for playing any kind of media file; and every time it was exactly 50-50 (meaning both sides were turned on). 

What I discovered this morning was that the problem temporarily disappeared: which means just out of the blue, both sides of earphones worked normaly....for some limited time; as I returned back later (for example right now), the problem persisted.

 

I have no idea what this could be. :-/ 

 

What I don't understand is what does trigger the earphones to suddenly just go deaf on one side...my best guess are the drivers, but I had them reinstalled just recently from lenovo.com which doesn't make much sense. 

I'll watch future events and try to see at what exact moment do the earphones stop working and let you know!

Thank you both for your support and effort!

Kind regards,
Pete

Re: G780 win 8.1 left side of headphones not working

Hi guys, 

 

Everything was going well up until recently. Guess what happened. Windows had some big update, because it took them a little under one hour to update .. I think it was around 200-500MB of updates (oh, and currently I'm smwhr with a bad internet connection). 

So, after the updates, the known problem described above re-appeared. Now I'm not much of a computer scientist, but now I'm really starting to blame something that seems connected to inconsistency between Lenovo and Microsoft Windows. Perhaps you guys should really work on that? I mean, it's not much work, but I don't want to reinstall the audio drivers manually everytime windows get an update. That's kind of a hassle. 

So what do you guys think, have any opinions? More over: I'm trying to reinstall the Conextant Audio Driver, with no apparent success so far. Please let me know how do I solve this problem. 

Thank you and kind regards,
Pete

Re: G780 win 8.1 left side of headphones not working

Hey Pssecho, sorry for the late reply, only thought that rang a bell at the moment is to run an OKR on your system aka the novo arrow back factory reset button

Hope that resolves the issue :/

Re: G780 win 8.1 left side of headphones not working

I'm a little afraid if I press that button, next things will happen:
- windows will go back to before updates
- all my files and programs will disappear

Could you please tell me the procedure to reinstall the Conexant driver? I know it has something to do with uninstalling it first and then finding it on D:/ .. however I forgot the exact procedure.
