Low FPS when headphone is plugged in

[warp]

It's Lenovo G510. It's not a gaming laptop but is able to run some games with OK frame rates.

Strangely, when I plug something into the headphone jack, FPS drops to less than 10.

It's got dolby software preinstalled. I am not sure what they do or how it interact with the hardware, but I doubt it's the problem.

Hareware wise, it's 2-3 years old since I bought it. It came with i7 4700 MQ, which is higher than its usual configuration for this model. I am not sure if this cause it to underpower with change in CPU and more ram.

(It had this problem since I bought it, but I ignored it since I didn't use headphone that much).

Any leads would be appreciated.

The only thing I can think of is your motherboards soundcard, maybe that could use a replacement, but dont take my word for that. I'm actually clueless.

Have you tried updating the drivers?

The audio processing is done on the CPU, just like the video processing. Once that processing is done, it passes that raw information for rendering and reproduction to the video and audio cards/chipsets. Game engines determine how many resources they can use on a computer based on threading.

What games are you talking about?

Yes, I updated the drivers, GPU manually (since windows 8 -> windows 10 it fails to recognize the correct version) and audio driver through windows update.

It happens in all games, tomb raider, l4d, dota. etc. When I plug in my headphone, after 1 sec, audio switch to the headphone and screen begin to shutter. When I unplug it, it's back to normal.

as you said motherboard sound card which is true. IF he would need to replace it, he would have to replace the MoBo. ever heard someone replacing his laptop motherboard? well it is more expensive then replacing the whole laptop.

basically what rotNdude said but you still have audio to process when using the build in speaker so it still seems strange

this is 3 years old but this is literally one of the only sources i can find, if you did manage to fix it is it okay if you tell me how you did. i get an average if 150fps in csgo but with headphones plugged in from the audio jack i get 100fps and high stuttering.

Although I'm not 100% sure, I think it's because the power adapter not supplying enough power so the OS/laptop automatically limit the speed to lower the power usage. This is just my guess, because if I unplug the power cord and let it run on battery, the problem disappear.

hi I know this is crazy asking because this discussion is nearly 4 years old but did you ever solve the problem and if so could you explain how because I am experiencing the exact same as you plus my mic doesn't work so I have resorted to Bluetooth headphones.

get the correct drivers for the sound card

and all the mobo drivers while at it from the mobo brand/model site
