laptop buz after 3 mins of recording

[Guest]

I have a compaq r3000 laptop, running cubase sx with steinberg's the grand
and one audio track. Every time after 3 minutes of recording it starts
distoring and buzzing. I've tried it with M-Audio Omnistudio USB with same
results, so it isn't a problem with the internal soundcard. Any ideas?

Maybe the fan when it kicks on.

The laptop starts distorting or buzzing or the audio signal starts
distorting or buzzing? If it's the audio, is it the grand signal, the audio
track, or the entire mix?

Three minutes? Repeatably? Could it be that your power management
feature is kicking in after three minutes of not touching any keys or
mouse? You probably need it set to "always on" for recording. Or keep
nudging the mouse...

I had this problem with my M-audio firewire 410
right now we are thinking Driver fault
I stopped using it

My M-Audio Transit USB goes into extremely loud "hissing" mode if
there is too much ground voltage differential across the USB cable.
(Too much being a few millivolts!)

If both your computer and the connected audio equipment are grounded,
try disconnecting the computer from everything but the cable to your
audio interface. Even the supposedly isolated battery charger can
provide enough grounding to cause problems with the Transit. Before I
cut out the 2.4 V power for cheap PC microphones, just the load that
caused with a normal line-in cable connected would cause the problem.

Dom't know if that has anything to do with your problem, but it is
worth a try.

would this apply to the firewire interface aswell
btw the hissing is not always there from the get go
it arises at a random point after recording but once present I need to
unplug the 410(from my mac) to make it go away

I would hope it isn't common to the firewire interfaces, or
Macintoshes, but what you are describing sounds exactly like the
problem I see with my Windows USB. Sometimes, if the relative ground
potentials are _just_ right, I can record for maybe ten minutes before
the hissing starts. If the ground offset is a bit larger, I may get
less than a minute. If I fix the ground offset, the hiss can
occasionally go away on its own, but more typically I have to unplug
the USB and restart the interface to be rid of it.

Hard to imagine what part of the system might show this same problem
on both Win/USB and Mac/Firewire!

usb = universal serial bus, cheap audio interface

compaq = cheap windows machine

have you contacted the suppliers you bought the products from for
custumer support ???
no one here has helped, all have been crying in their beer with you.
cheap schaffer beer probably!

The original post was about a Firewire interface. I added the comments
about my USB device acting similarly. Are you saying both of us should
have gone with PCMCIA? Is there any other notebook compatible choice?

>compaq = cheap windows machine

Depends on the model. And what does the price have to do with it
anyway?

>have you contacted the suppliers you bought the products from for

I spent almost a month, and many hours of effort, trying to get help
from M-Audio. None of it made any difference. My computer vendor has
no idea why an M-Audio product doesn't work.

>no one here has helped, all have been crying in their beer with you.

I solved my problem by cutting away the 2.4V microphone bias, and
learning that I can't have any ground offset across the USB cable. I
haven't heard if that helped the guy with the Firewire unit.
