lenovo 3000 N100 stuttering audio

Has anyone experienced stuttering audio with a lenovo 3000 N100 (or similar laptop that uses the Realtek ALC861 HD Audio Codec)? It occurs in both Vista and XP, even on a fresh install it will stutter while booting into the OS. I have tried the lenovo-supplied drivers as well as the latest drivers from Realtek's website. I even tried different Media Players (9, 10, 11) and different file types (mp3, wma, wav, video files too).

I contacted lenovo and they don't seem to know what it can be. I contacted Realtek too, but haven't heard back yet. Lenovo suggested that I send in the unit to be serviced, which kinda sucks being this is a brand new laptop.

 

On my HP when I start up a new processor intensive program such as Photoshop or a new game while I am listening to mp3's, the audio will hiccup for a second than return to normal.

Is this what you are talking about? I think this is more related to the CPU having to handle multiple processes, so it momentarily diverts some processing power away from the mp3 music player.

 

Not really, because it occurs when I'm not doing anything else but playing audio.

 

Mine is lenovo N100 too. XP Home. There is no strange sound while booting.

 

I am having the same problem on my T23 under XP. I've downloaded & reinstalled the latest audio drivers from Lavino with no success. At first I experienced it under video & I figured that the cpu demands were too excessive, but when it had the same intermittent stutter while playing .wav & .mp3 with no other software running I knew that there must be some other issue, as my 300Mhz IBM laptop has no problems with .wav or .mp3 files. I suspect that it may be a Microsoft Driver issue.

 

I have Lenovo 3000 N100 and we're having the same problem. I thought Realtek codec and NVidia Graphic are causing this problem but I just found out that the stuttering accurs when the Broadcom wireless network is turned ON. I hope there's a firmware update for this because I can't use my Skype properly since the stutter can cause audio delay and cut off the sound a little every after 20-30 seconds during phone conversation but they heard me clearly without any problem.

The stutter also gave the CPU a hard time while I was watching Hi-Def videos from vimeo.com so I just let it finished the downloaded stream and turned OFF the wireless network.

 

I just found a solution. I unplugged the wire (either white or black wire) connected from Broadcom Dual-Band 802.11n PCI Express MiniCard inside the laptop and stutters gone. I'll try to find a replacement maybe the Wireless MiniCard is defective.
