Getting terrible sounds from Lenovo T520 thinkpad

[kEyURi]

I have purchased the new Lenovo T520 thinkpad two months ago. I like the design and the model of the device so I purchased it. I am new to this kind of device. I don’t have any problem with the working of the device till last week but after that I faced some serious problem with it. Actually the problem is I get the terrible sound when I play any file in the Windows Media player, Firefox or IE (java, YouTube) etc from my speakers. The constant pops, hisses, crackles and pauses is often for my system. It is very maddening. I also try to use plug in a USB headset (plantronics audio 626 HD) but the problem remains same. I cannot understand what to do. Can anyone give me some suggestion to solve my problem? Please help me.

It would encourage spotting the foundation for intrusions in certified-time sound and motion picture streams, additionally reputed as drop-outs.

I read your problem and then I searches the solutions on the web. Then I come to know that this kind of problem is mostly found due to one reason. Here I am giving you that reason. This problem is found when the Nvida 4200 is enabled in your system. so I am giving you an advice to disable that.

When you try to move the mouse with the USB connection or suppose you are typing a lot then that will generate the more DPC spikes during popping and crackling. Otherwise there is no DPC spike. But I think that will pop and crack. I think this will give you some idea to solve your problem.

It will give a conceivable report and identify the portion modules and techniques which are answerable for initiating sound latencies which effect in drop outs. It likewise furnishes the purpose of an ISR screen, DPC screen and a hard page fault screen.

This can provide you more specific data but it will just confirm the issue at hand. Then you have to run it for a while then go to the drivers tab then you have to sort by DPC count, and paste a screenshot. Or you can try to uninstalling everything NVidia from the control panel. In this way you can solve your problem easily.
