Buzz/Humms while using certainf Software, it gets weider!

[bror31]

Hello guys how are you? I'm Bruno, new in the community, looks like a interesting forum to be part of. I;m at the moment using a Octane VI purchased in March this year from PC Specialist. The laptop works excelent in every aspect exepct of what I'm gonna write below:

So.. I'm having the wierdest issue with my speakers and edit software at the moment. Let me put you in context: I have an Apollo Twin Duo USB, and the speakers are Presonus Eris 8. The apollo gos via USB 3.0 to my laptop. I was usuing it without problems since I got em, but the last two days I started noticing a buzz/humm when using photoshop, but it was not always there, the buzz was when I adjusted any valu with a slider or curve. For example If I was using the photoshop Curves, while i holded the mouse down and move the points I could hear a very loud buzz comming through the speakers. I tried the same with other software (Davinci Resolve and After effects) and was the exact same thing, the bbuzz through the spakers was there, but only when adjusting parameters graphically. I tried the Headphone outpu of my apollo and the buzz is not there.. only throu the speakers. Now here comes the very wierd part of the story. I discontecrted and turned off the Audio Interface, so now the speakers where ON but unplugged for any digital source (not conected in the pc) yet, when I adjust the parameteers, the buzz is still in the speakers... is like a interference, but I cant determine what is causing it. Does anyone have an idea of what can be going on?
Thanks very much for the time reading this!

That is interference and nothing to do with Windows. In the early days of hi-fi audio systems (like 50 years ago) mains hum was a major problem and usually caused by earth loops. I suggest you experiment with both the relative location of your laptop and speakers and the actual location in your house of the laptop and speakers, so interference of this type is nothing new...

Does it also happen when the laptop is on battery power only (with the charger unplugged from the laptop)?

UBU thanks for the reply, havent got time yet to try all that but I will over the next days and get back to you. i still fin it wierd that is only while runing certain software aeven is there is no conection between speakers and laptop, but worth a try. I'll keep you posted and thanks you very much again!

Is your mouse wireless?

This is less strange than you think. The noise comes when the offending connection is being used more intensely. For instance, if it's the CPU chain that the ground relates to then it will get noisy as you ramp up the CPU usage.

You could do a test on the CPU using a torture test or benchmark utility. Similar with the GPU, that way you could somewhat narrow it down.
It would also be the screen where bright whites often use more power. Open paint, white background and turn your monitor to full brightness.

Hello, thanks again for all teh replies, I did loads of the test, and the problem seems to persist in any situation. I do have wireless mouse, but I even isolated the laptop, run energy only through the battery, and the usb 3.0 to the Apollo twin. no external monitor, no usb port hubs, no periferic at all, just audio laptop (battery plugged, not ac) audio interface and speakers, and the noise still there when I run any software that requieres gpu usage. Notice also that even if the program i not overloading the GPU, it stills makes noise. Example: Using curves on photoshop to correct a 5mb image.
I should have mention Im runing a i9 andt he video card is a RTX 2070 (yup all in laptop)
So after researching in forums seems that GPU can make that intereference. Do you think is that? Is any way to solve it?

I think in that case I'd be tempted to call PCS. It might be a hardware problem in the board?

At least it's narrowed down to likely being the GPU circuit/interface. As above, time to contact PCS. You have all the relevant info to warrant a return.
