Poor audio from headphone jack y40-80

Immediately whenever a headphone or earbud is plugged in, the audio is crackly, until I go to the realtek audio manager which doesn't have many options. once I change the Left-Right balance to being very one-sided, the cracks and pops don't occur anymore. However all of the balance is off, voices are not audible, and SFX or background music/tracks are output very bad.

Testing the left-right balance, both play the same as if the headphones are mono audio.

Re: Poor audio from headphone jack y40-80

Hi there, Ray -


Thank you for writing in to the Lenovo Forum - happy to have you here today.

 

Did you check headphones with with different system?

Check your speaker and headphone connections for loose cables or the wrong jack.

Check your power and volume levels, and try turning all the volume controls up.

Also, try updating the BIOS

 

Update us how it goes.

Re: Poor audio from headphone jack y40-80

I've tried three different headphones with the system, which I normally use on my desktop PC and works fine.

 

There are no loose connections, or any sign of physical damage to any parts of the laptop or the headphones, I've also played with the power settings, volume control, looked for audio drivers/updates and controls, even brightness for some reason.

 

I haven't tried updating the BIOS yet, though. I'm running Windows 10 64bit, will the update still work?

 

Thanks

Re: Poor audio from headphone jack y40-80

I assume you're using onboard audio that’s integrated on the motherboard. This is due from the lack of a good SnR ratio (Signal to Noise) and possible interference.

 

Click here for Audio drivers.

 

First of all, make sure it’s set for headphones in the settings. Turn your media player, game, etc. to med-high/max volumes within their settings and don't have the actual volume of the computer up too much.

 

Update us how it goes.

Re: Poor audio from headphone jack y40-80

Thanks for the advice!

 

I reinstalled the drivers.

By settings I hope you mean the Realtek HD Audio manager, or the Sounds/Playback devices. Either way I looked at both and neither give me a setting for headphones. Both label my headphones/earbuds/IEMs as "speakers" and there is no option for device settings, only for setting certain devices as default.

 

I tested it anyways with the recommended volumes, and the problem still exists, with the audio being very imbalanced and full of static.

Check setting the BIOS to factory default & to proceed with this, boot the system into BIOS by tapping F2 key on Lenovo logo, press F9 key to set the BIOS to default & F10 to save and exit.

 

Also, try cleaning out the headphone port with a can of compressed air?

 

Update us how it goes.

Couldn't press F2 to go into BIOS, had to shutdown and use the Novo button next to the power button.

 

Default did not change anything, and compressed air didn't blow anything out of the headphone port.
