Problem with my 828MKII ?

Paul.E · 7th February 2005

I'm not sure if this is the right forum to be posting a technical issue but if it isn't, feel free to move it.

Well I've had this problem for a while now, probably ever since I got my MOTU 828MKII interface. The sound quality is good going in and comming out, the problem is that often, regardless if I'm working in Cubase or simply listening to music with Winamp, after some time operating normally, I start getting clicks and pops in my sound. I haven't been able to pinpoint the cause of the problem or when exactly it begins. Sometimes after a quick series of commands such as STOP and RETURN TO 0, or quick pause/play commands. Sometimes closing the program and re-starting does the trick or also rebooting the unit.

I doubt my computer is the cause of the problem. What do you think?

things...to try...

have you got the latest drivers from the motu site (latest were last august iirc).

have you got 'system sounds' turned off (i'm assuming your windows based). Could be that a beep or email notification sound tries to change the sample rate.

in cubase, what's you latency..have you set it too low..does the problem go away if you increase it.

are you running any other apps in the background that could be trying to use the 828 ?

Negative on all points. I'm running Windows 2000 Pro, pretty tweaked for my applications.

Here is an example. I could be simply listening to music with Winamp, computer at idle (not touching kbd or mouse) and it will suddenly make a really high pitch noise, then a tiny bit of silence, then it will continue normally. Or after that noise, the sound will resume but very... grainy, noisy.
I'm not clocking externally.... Could it be the internal clock thats f*cked?

Thanks for your help, turns out it's probably the Firewire controller that is causing this. It happens to be a built-in controller on my MOBO. I will pick up a PCI card today and pray for the best.

sorry, should have mentioned that (there were two 828mkii threads running at the same time ).

motu does seem really fussy about the firewire chipset...somewhere on the motu site there is a list of recommended chipsets, might be best to consult that to be sure.

I had that problem at the start when I had it. I don't remember, but at the time I did format my pc and start a clean slate, but if I remember correctly it was the driver updates that help.
I think I remember looking at the motu site on the frequent asked or sumthin like that.

hope that helps

There we go!

Thanks guys. The PCI card I am getting uses the TI chipset so it should work great.

This is bullshit! I got an ADS Systems PYRO DV firewire card, and the problem persists.

However, an observation that I made may help you guys, help me! By the way, I tried the 828 on my laptop (an Acer Travelmate 290 with Pentium M processor) and I did not have the same problem.

This interruption/high pitch noise is totally random but I figured out a way to provoque it. I can open up Notepad and simply bash my computer keyboard quickly (typing nonsense) and this somehow occasionally triggers this "bug".

So, that being said, it's obviously a problem with my DAW. What can it be?!?!?
