Hi Everyone,

First post and I'm asking for help , apologies. Just bought a shiny new 828mkII usb for my PC and I'm buggered if I can get it to work properly.

For various reasons I'm stuck using a PC and Adobe Audition 2.
On recording I'm getting drop outs and stutters, on playback I'm getting delays and crackles etc...I have tried everything I can think of, uninstalling pretty much everything but the 828 drivers, thge machine is well spec'd, all services not required are off, flattened the machine and started fresh...it's a dedicated machine with enough muscle and still I'm struggling.

I'm wondering if it is this XP SP2 problem, if it is I'm ruined as Audition needs SP2 to run...before I take this card back to the shop, could anyone suggest what I might be doing wrong?

Any help would be much appreciated.

I too am suddenly experiencing Noise out of the blue! I have no idea why this has started and I'm very alarmed. Sorry I can't help, but I'm hoping MOTU will look into this since this is clearly not a one-off!

decent setup on the rig.
have you tried the samples per buffer settings?
i have to have mine set at 512.
if nothing happens there, then pm me i have the sp 1 roll back in a zip file.
i can fire it off to you.

Thanks for the reply, very much appreciated .
What exactly does the service pack roll back , roll back?

it`s all the setting for the 1394 port and "language" that windows uses to "talk" to the fire wire port.
as well as how to access the port on the bus.
windows does not do any "direct" hardware calls, unlike linux or older mac ( pre intel chips ) it "talks" to the hardware through drivers ( translators, have you ever looked at a dll tree? translators for translators. )
to make a long story short, it uses an older language that works. lol.
before microsoft decided to change the dialect.

Same problem here with similar spec. PC.

This is seems was directly linked to USB problems. I was using a USB keybord and mouse which when I unplugged it fixed the problem. Using a standard PS2 mouse and KB and all is well now...

doesn't really solve the issue, it is clearly an issue with USB interrupts configured on my machine.
