noise from speaker when computer is processing

[Dave12345]

Does anyone else get a noise from there speakers when you resize a window in XP or process some audio ? I am using a Rosetta800 with the x firewire card. Its only very faint - i've never heard it before with my other firewire sound boards

I have had this problem when using on-board audio cards, but never with a rosetta.. Although it could be the same problem. Sometimes if your audio card or firewire card is too close to the motherboard buss, you will get noise as a signal is passed by the card, due to the fact that the pcb is all open and not shielded to crosstalk.

• You could try changing which pci/pci-x slot you are using.
• If you are running a long firewire cable and it is cheap, you could have a shielding problem but i highly doubt that is the problem

it could be fault of speaker/amp shielding

When I use my dell laptop with yamaha HS50m, I get really loud computer garbage... or more correctly noise from switching powersupply, because it stops when I run it on batteries. But pluging Adam S3A to the same config and it is 100% clean.

Try not to let computer data cables run parallel with audio cables. I had this same issue with one studio and some cable rerouting fixed it right up.

I have had a similar problem with my MOTU 828mkII and my Dell laptop -- but only when the MOTU and the Dell's internal soundcard were BOTH hooked up to (different inputs on) the same control amp (a Yamaha prosumer receiver).

Similar to your situation, I would get odd whirrings and chirps from the speakers where there were certain screen events, sometimes clicking on a web page or going forward or back through page history, and so on. It doesn't matter WHICH sound device is active on the monitors -- I'd get pretty much identical sounds from either.

The solution, of course, was relatively easy if not entirely convenient -- simply unplug one when the other was connected.


Because of this issue, I made a point of buying a Texas Instruments chipsetted Firewire PCI adapter (as recommended by word of mouth as well as MOTU themselves) when I switched primary operations to my then new tower and I've had no progs (knock on wood) with that box, even with both the mobo sound interface as well as the MOTU 828 mkII hooked up to the amp.

This is actually a ground loop problem believe it or not.

People with laptops will find it goes away when you run the laptop from it's batteries.

All I can suggest is using balanced cables and having a swap round with your mains plugs.

sound on sound (soundonsound.com) did a good article on this once, you could try there.

thanks for this. i've worked out that it is my coleman audio ps1a causing the problem. anyone else have this problem and found a way to fix it ?
