network adapter on windows 7 causing latency and sound distortion

This just started three weeks ago and I never had the problem in the three and half years running the desktop computer. When I browse in chrome from one site to the next the sound distorts on You Tube or from my Spotify software. I used the DPC Latency Checker and discovered the problem is in the Network Adapter, but that has the most recent update.  I would appreciate any suggestions.

RE: network adapter on windows 7 causing latency and sound distortion

Hi,

A couple of quick, and maybe crazy, questions.  

First, you said this happens in Chrome.  Does it have the same effects in Firefox or IE?

Second, are you using internal speakers or detached?  If detached are the speakers located close to the system (and thus the network card?)

Third, are you using the broadcom NIC for your internet connection?   Is there a network cable plugged into it and, if so, is your network connection sluggish or does it seem to still work as normal?

Fourth, when you say you are browsing from one site to another does that mean you have youtube or spotify running separately (or in another tab) so that it shouldn't be affected by loading another webpage?

It could be that there is some sort of short, or electrical static, in the NIC that is aggravated by data flowing through it as you access new pages, and that is causing the static / interference in the speakers.  But I would think if that were happening you would see an issue with the internet connection and speeds as well.  Unless the network cable has the plastic / rubber shielding around the wires fraying away, exposing the wires within it.  

What happens if you physically move the speakers further away from the NIC?  Does the distortion lessen?

Let us know the answers to the above questions and I'll see what else I can think of to check.  

Todd

RE: network adapter on windows 7 causing latency and sound distortion

Hi Todd and Martin,

I have the same problems with Inspiron 15R SE 7520. I have latest drivers on Windows 10 64. I discovered also that network driver is causing DPC latency problems and audio is playing very poor with lags. That's crazy. So good computer with i7 is not able to use network over cable and play sound...

When I play from local music source, also I see the context with bad network driver, because shuttering is casused by network traffic for example by browsing in any browser.

I think we really need new Realtec and Conexant drivers, because they are seriously bad. Or any trick how to set up the current configuration and windows timers. May be the possibility is set low priority to network.
