Sound Breakup when CPU is utilised

When my CPU is barely utilised, there is no problem with the sound
generated (my sound is built-in on the motherboard).

But when I start using the CPU, the sound breakup.

Can anyone give me some hints how I can troubleshoot this ?

Thanks.
 
I suppose a first step might be to visit your motherboard site, or PC maker
if a large OEM eg Dell / Hp or Laptop and ensure you have the latest chipset
& sound drivers
 
I've updated both. But it's still happening. I notice that it's not
due to CPU utilisation as I wrote a small batch

:repeat
goto :repeat

and I run this 2 times to use up my Core Duo.

When I play the MPEG, the sound is not distorted (choppy).

But when I have high harddisk (SATA) activity (eg copy a very hugh
file from 1 SATA disk to another), the sound is choppy. Not only
that, when I play the MPEG using WIndows Media, the whole play slowed
down and it choppy. I wonder if this is correct behaviour and that I
should leave it alone.

Or could be some settings, caching that I should tune. I understand
that for SATA, the DMA is on by default and cannot be adjusted.

Please advise me. Thanks very much..

I'm not sure, but perhaps run dxdiag, the direct x diagnostics tool - it
also reports on sounds
 
Hi !
I've done the diagnosis. No problems.
I've called support for my motherboard. They says that when the
CPU utilisation is high, there would be choppy. How can I determine
the choppiness in my situation is due to CPU utilisation and not due
to the problems ? Any advice ? Thanks.
 
Open Task Manager and watch the CPU utilization.

I've already done that. But my question is how do I confirm that it's
due to the CPU utilisation and not something else (which could happen
at the same time when the CPU utilisation is high) ?
 
Look at WHAT is causing the utilization.
