Yo - So I had this old Rage card and I got glitches in the audio whenever there was heavy picture movement on the monitor, and even with my new Matrox dual VGA card, I am having this problem. Both cards are AGP. Any thoughts? I read k's article about this, but he only mentions PCI cards. Are these the same in this instance, sharing PCI bus? If not - how do I fix this problem? Thanks.

Only thing I can think of is, in your bios, check and see if there's an option to "assign interrupt to VGA"... try disabling that. I think that somehow incororates it into the PCI bus? Wow, I'm really making things up here, but it all sounds legit...

Make sure they aren't sharing IRQs.

Nope - the vid card is IRQ 16 and the audio card is IRQ19. Only shared IRQ's are for my USB port...

Onboard sound on the motherboard ? If so is it disabled ?

How do I check DMA enabled?

No onboard sound on the mobo so nothing to disable there.

right-click on My Computer, select "properties" Select hardware tab. Click "Device Manager" button. You'll see a tree-type view with all your hardware. Open up "IDE/ATAPI disk controllers" and double click on "Primary IDE" (and also "Secondary IDE" in turn.

There should be a dropdown under "Advanced Settings" that should be set to "DMA" or "DMA if possible".

If you find the dropdowns and they're not set to DMA, set them.

If you don't find dropdowns, or there's no choice for DMA, visit your motherboard manufacturer's website and download updated drivers for your motherboard. These should enable DMA.

right click on the desktop, select "Properties" Pick the "settings" tab, then click the advanced button. Find the slider for hardware acceleration (mine's under "Troubleshoot"). Drag it all the way to the left (no acceleration).

Any difference?

Hey Craig - It was set at full acceleration so I moved it to none. Next time I started Sonar, it had a problem with my audio card. Would this inhibit my audio card in any way?

Ack - I just rebooted using "none" (as opposed to full) and I still got a drop out when I minimized Sonar and when I minimized the Console view. Gotta be something else.

Well, I'm searching through the Sonar support forum and it seems that there is a resizing bug that will be fixed before the new year. Hopefully, that will take care of it. I'll keep you posted - thanks for all your help guys. Much appreciated.

Oh, yeah... I never do anything like that while playing/recording. Just use the view I'm working with or switch to the staff view from track view. Sometimes there's a delay in the new window showing, but not usually a dropout or audio glitch.

Such things are an annoyance though.

Matrox cards can be bus mastered. Meaning that they can control the PCI Bus (for games and video editing). Turn this off.

i know this is fairly obvious but i thought i'd give it a shot... did you make sure you're using the latest driver for your video card?
