Interference

It could be a driver issue or it may be that your wi-fi is on.

It's a pretty common symptom when something is competing with the mouse on the bus.

I suggest that you edit you thread title to include "Mac", "Mouse" and "audible interference" or "noise" and someone who is familiar with your set up may be able to recognize your issue and provide a specific solution.

Good Luck.

mike brings up a good point turn off your wi fi in devise manager.
then download this and start disabling things one by one.

its the dpc latency checker..you can use this to sometimes isolate a problem

Besides what's already been stated, it could also be noise injected into your power supply from the VGA card. A lot of display adapters aren't filtered very well. Seeing that it's an iMac you won't be able to move around the internal power cables and integrated sound cards usually don't have the filtering required to reject this noise.

If the Wi-Fi doesn't solve the problem it I'd recommend getting an external audio interface that has it's own power supply. Bus powered devices may still exhibit the behavior.

Are you using the built-in audio interface?

I'm using a VS-100.


Thanks

Do you mean turn off the Wireless Network Adapter? Very new to all this so thanks for your help.

I have the same issue with my iMac.  Mouse noise etc. through my monitors whether they are connected directly from the iMac or through my interface.  I've unplugged everything, lifted grounds, moved the speakers, cables, plugs etc. no change.  This is my 3rd set of monitors.  I have not tried balanced cables yet though.  Would that make a difference?

It appears my issue is the same and my wireless is disabled.  I also tried turning off Bluetooth and connecting a hardwired mouse/keypad and it did not make any difference.

have u tried running the dpc latency checker?

It does not happen with headphones or on the internal speakers.  It does happen whether I use a separate audio interface or run directly from the iMac.  I've tried unplugging everything, lifting the grounds, and moving the speakers around etc.  It will not stop, very annoying.  This is the 3rd set of monitors I've had this with. (1st two, Samson Resolv's8, this set, Yamaha HS 50M)  I did try an old (15year old Vestax) little 8W monitor pair and it did not happen with those--very interesting. I don't know what is different other than the new monitors are much higher powered.  If someone could help me solve this I would be eternally grateful.

If you use an external audio interface (monitoring via headphones), do you hear the noise?
If not, I'd put my money on a grounding issue.
 
Crap USB cables can also result in strange (digital hash) noises.
I once had a noise issue that traced back to a Motif ES.  The culprit was the USB cable connecting the Motif ES to the DAW.  Swapped the USB cable for a higher quality cable... and the problem (noise) was gone.
