Dell OptiPlex 755 Ultra Small Form Factor, noise from audio-card/video card
I put an OptiPlex 755 USFF for video conferencing. We have an issue that when we have a rather high volume on our speakers, we can hear a a bit of noise coming from the video card.
We practiacally hear data being written to video ram, so there seem to be some kind of issue with the data bus and drivers.
Can Dell please look into this and update their drivers? I guess the problem really lies with the video card drivers

First, this is a users helping users forum, not a direct line to Dell support or engineering. You will have to contact them directly if you feel it's a design problem.
The noise you hear at high volume levels, could be feed over from the data line, from something on the other end of the conference, or depending on what instrument you are using for the conference it may be it is not well shielded and picking up RFI from the PC (and in that case the conference device is the issue). Devices such as computer speakers are shielded to minimize RFI and if non-computer speakers (ones that are not shielded) are being used that can be a source of the problem. Try locating the PC further away from the conferenceing equipment as a first step.
But, it's not a "driver" issue.
