Ideapad y470/y570 audio stuttering [ Edited ]

[Yanm]

Hello everyone. I recently got my Lenovo Ideapad y470 this Friday and I love it so far. http://shop.lenovo.com/SEUILibrary/controller/e/web/LenovoPortal/en_US/catalog.workflow:category.det...

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.

Anyone? I'm still trying to see if this is something I can solve myself without having to send it back to Lenovo for them to check it out.

Hi...

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.

It still stutters with the battery in or out. I've ran Youtube, and Windows Media Player without the Nvidia and on Balanced, yet it still stutters. It also stutters on High Performance and with the Nvidia enabled. I did read that thread, and I'm curious about that. As far as the drivers go. . .I'm guessing the audio would be the problem and I have the latest version that Lenovo offers. It could be something else though maybe? Also, I'm always hooked up to my router, so I'm wired constantly. I'll get around to checking if wireless lags me.

@All,

Interesting problem here.

Try using DPC latency checker, play the audio then when it stutters, check the DPC software and see if there are any red spikes.

If there is, try disabling Nvidia in device manager and see if it helps.

Hi all

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.

http://www.realtek.com/downloads/downloadsView.aspx?Langid=1&PNid=24&PFid=24&Level=4&Conn=3&DownType...

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.

Cheers 

Peter

try to update audio drivers

[Liquidsnake]

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?
