Could you describe the noise?
It almost sounds like background noise that can happen when the audio isn’t shielded. This normally sounds like hisses, clicks, pops and can often vary with system load.
An easy way to test this is to disable the audio in the EVE client and see if you still hear it. If you did, that would indicate it’s not the EVE client causing the audio directly.
The load on CPU causing the noise is EMI. It’s a very common issue with onboard sound. Many people use USB soundcards to help with this.
The 100% CPU usage that you’re reporting with EVE is something we’re investigating. We’ve not been able to reproduce it in house yet. I’m speaking to a number of people in the community who are experiencing it to try and reproduce it. I’d ask you to file a bug report so we can get your system info, as this issue seems to be very user specific. Feel free to tag me in it if you do.
