Windows Virtual Machine Question

by vrygreen / December 23, 2012 7:15 PM PST

Hi,

I'm running Windows XP Mode through Windows Virtual Machine, with IE9 and Win Exp 7 Pro. I'm using a music recording software called Protools LE 6.4, and I'm running it through a hardware called Mbox (original). I can get Protools running, but there's a lot of interference going on. The interference is worse when I drag the mouse across the screen. It is there even before I crank up the virtual machine.

I've isolated the speakers and also the cable and it's not coming from either. It's definitely associated with the Mbox.

Any ideas as to what might be causing the problem?

Cheers
VG

Clarification Request
Can you maybe tell us a bit more ...
by Edward ODaniel / December 24, 2012 1:14 PM PST

about your specific computer such as make and model and how much RAM it has? Amount of RAM has a very direct effect on running virtual machines (hint, 2 GB doesn't go far) and other components can be stressed also.

Hi Edward,

I'm using a Toshiba Satellite Pro 64-bit, 4 GB RAM laptop. Since posting I've been told to test it by removing the power lead, which solved the problem. Apparently, there's an earth problem with this laptop/lead. I'll have to talk to someone down at my local computer store.

If you are familiar with this problem and can point me to a simple solution I'd appreciate that.

Cheers,
VG

Ground problem

Earth problem, you mean "grounding" issue. Then that should be resolved by replacing the laptop AC power charger/adapter. If this is only a 2-wire setup. maybe a 3-wire one will do better or flat out replace it. Overall, I just wouldn't think this is a problem as that suggests a broken or weak connection or a mis-wired home. Besides the laptop any device that's attached, if it is somehow "grounded" wrong or using chassis ground vs. true earth ground then you have what is called, a "floating ground" issue. That implies a minor voltage isn't being properly disappated or grounded quickly enough and/or electronics path are present before it be dealt with. A real tech or electrician should be able to point out the cause or help. You can buy a simple 3-prong wiring tester from Radio Smack and its LEDs tell what's what for basic test at wall AC outlet.

appear to be fairly common and ground based.

I did locate this link that appears to provide a lot of information and suggestions for the problem you describe and a quick read of it indicates that a Behringer DI20 (pretty inexpensive as the following shows https://www.google.com/search?q=Behringer+DI20+Ultra ) is a good solution.

Hope that helps but since I can't hear I don't pay much attention to sound problems or solutions.

Thanks, and I'll keep you posted.

Thanks Willy and Ed,

I'm going to take the laptop and Mbox down to the store and see what works best. I came across that "sound on sound" post after I posted this; it's a good post. I'll post here again when I've solved the problem.

Thanks again for your help.
