Lately I've updated my Intel Graphics Media Accelerator Driver to version 18.104.22.168.2509.
After the upgrade I've noticed improvement in DPC latency during idle and audio playback.
But once I access internet (via Chrome browser) DPC latency and its accompanying audio stuttering problem returns.
I'm wondering if somebody at Lenovo is working on resolution of the sound problem in these multimedia laptops?

Check that the CPU usage if is at 100% when the shuttering sound appears. I had the same problem, and it was caused by McAfee antivirus. After uninstalling eveything was ok, no more strange sounds.
Hope it helps.

I have tested out Helsad's suggestion, and am happy to report that I haven't had a single audio stutter since I uninstalled the McAfee antivirus! Lets hope its stays this way. Dunno if this will work for everyone, but thanks for the suggestion bud.

i have the same problem i send a mail to lenovo support , but after a week no answer to the mail , i have tryed everything, i saw that disabling wirelless , and the second is pluging out the power supplier , in this 2 conditions the stuttering is gone . maybe the problem is the wireless driver , i dont know. what i have tested was to boat from usb knoppix and there the sound is very clear ... strange . anyway try to see if this work for you guys , i wait a solution to this problem i use almost all day to external speackers and is very anoying . So please lenovo engineers do something with our sound !!!

geo_lion03's problem is probably unrelated to the current thread. It probably reffers to the constant noise when using the audio output, which is probably caused by poor (magnetic) insulation.
It's still a bit early to say for sure but apparently the problem has been resolved by removing Norton Antivirus. I'll come back with a reply if it still shows up.

thanks for replay , it s true that is a constant noise when i use the audio output , and i m so disappointed because of this problem , i love to use my powerfull external speacker to listen music , and in my old laptop i never had such a problem , i love this laptop but ... this drive me crazy , and what i had noticed last night was that if the laptop is plug out this reduces noises, isn t any solution for this problem? i mean a new bios or audio drivers fix , wi fi audio driver fix etc ... it s a hardware issue? because i don t feel to send it back to service , i read about some who had this issue and after back from the service the problem still was present.

I have a Y570 and it came with a free 30 day trial of Macafee, as I am sure all of yours have. I noticed the sound jumps (and simultaneous CPU flare to 100%) when I got it and assumed the problem would be resolved in a BIOS or driver update. It kept continuing, but now that I think about it since my Macafe trial ended and I have been working solely off of MSE (Microsoft Security Essentials) I do not think I have encountered the sound issue. This is sad considering Lenovo gives us this expensive security software. I was talking with the Geek Squad guys at Best Buy and they claim that they have stopped selling Macafe because of the evident problems it causes. This may not be the problem, but it seems like many people are raising flags to indicate that Macafe is a serious contender to the issue.
