audio crackles when video is being played

[yesterday]

Hi guys,

I just recently clean installed windows 7 on a machine I built myself and now every time I play videos on the web on full screen I get crackles from the sound. Youtube crackles a little bit when opening a video into fullscreen and then quitens down when I stop moving the mouse but other sites with video crackle all the time, like 40d or any other video streaming sites. Even windows media player crackles when I'm playing music with visualizations in full screen or small screen.

Watching videos in vlc though do not give crackles in full screen or small screen.

I have tried updating my graphics card which is a  Nvidia GeForce 8400s updating the sound from the built in motherboard (ASUS P5b-vm se) but still nothing. Sound was working fine until I clean installed windows 7. I've checked all the cables many times but I still can't figure it out, any suggestions?

Thanks

Crackling is the connection/wires/speakers...
Can you borrow another pair of speakers to test ? ?

I tested the speakers using just an mp3 player and the speakers and they worked fine. Sound works fine, it's just that when there is full screen video with it that it crackles. I thought it was a problem with the cpu being overloaded but I checked task manager and the cpu percentage usage is low around 10%. I also ran DPC Latency checker and it reported very high latency.

Well i'm not sure what's causing it...but i cannot see latency issues producing a crackling sound at all...

Best of Luck.

I have seen USB Powered Speakers do this before... Are these speakers powered off of USB? If so its noisy 5V power at USB port. Solution then if this is the case to get one of those power packs that allow you to charge USB devices off of them and plug speaker USB power into one of these to power the 5V to speakers.

Systems using this USB powered speaker setup also experience noise when moving mouse and speakers are max volume with nothing playing. You will get noise from the mouse communications causing a ripple to the speakers which are powered on the USB port along with mouse.

Hi thanks for you suggestions, I solved the issue.

The speakers were not usb powered but they were powered from the mains.

I read somewhere that updating the bios could help, I updated it and it was solved.

A BIOS update fixed crackling speakers ? ?
Another new one on me.

Glad your fixed up...

On-board sound problems. Seen this before, but chiming in too late.
