Hello everyone. I recently got my Lenovo Ideapad y470 this Friday and I love it so far. http://shop.lenovo.com/SEUILibrary/controller/e/we
I got the 085525U version. My problem is that whenever I'm watching Youtube or playing any games/audio I'll get a random stuttering that lasts for .5-2 seconds. Recently today, I did some more research on it and I tested that it only seems to happen with headphones. When I used the normal speakers, it was perfectly fine. This is a minor annoyance to me and I was wondering if there was any way to fix it. I read somewhere that getting rid of Lenovo Power Manager works, but I can't seem to find it under Control Panel. I also read that playing without the battery in fixes the audio, but I have yet to test that. I'm on a wired connection by the way.
Thank you for your time.
EDIT: Nevermind, it also stutters without the headphones in. Can anyone help me solve this? Again, I find it a minor annoyance and it is tolerable to an extent, but having it stutter every now and then can get annoying, especially during gameplay.

does removing the Battery Pack and then using mains power only make any difference with audio stutter?
may also troubleshoot with WLAN & Bluetooth switched off in Lenovo Wireless Device Settings
and the little switch on front of laptop,
then in Lenovo Energy Management select High Performance, under Display and System tab
set everything to Never and Maximum CPU Speed to High.
Try to find out which settings influence the stutter, possibly just need to update the relevant driver.
Good Luck.... Zehn

I can confirm this "bug" as well, happens without headphones, on High performance and plugged in. Never tried without wifi/bluetooth since I need them anyway. Happens randomly, once every 10 minutes or so.
A fix would be nice since this is kind of annoying.

One of my friends normally uses Realtek original drivers with his y460p and it works without problem.
Some of my friends also tested running latest OEM Realtek sound card on their Fujitsu or other laptops which does not fix issues, but downloading the latest Realtek drivers resolves it. You could try.
Realtek is quite similar to Nvidia, which releases new drivers frequently which fixes problems or enhanced performance which oem normally do not keep updating. = Either you get not so great sound or buggy issues.
Does someone post helps you? Give them a kudos as a reward, as they will do better to improve
Mark it as solved if the solution works for you, so it could be reference for others in the future

The lag shows up in DPC and it says that there is a problem with one of the drivers.
However installing the realtek version does not fix the problem. The bios on the Lenovo website is older than the installed one so I don't know about that (which is really odd considering there's no CD that comes with the laptop).
I'll try removing the battery but that's not a real fix anyway.
Edit: By the way, when you're reffering Nvidia, do you mean the display driver?
