Hi
I use an ASUS p4pe Mobo.
Whenever i play a game like halflife or
doom3 with the CD in, my PC makes all
these beeps and bloop noises,from the
pc speaker.
Anyone know how I can stop these noises? Thanks
Are you referring to keyboard overflow ?
If I hammer enough keys on my keyboard, the little case
speaker will beep.
Are you referring to the case speaker beeping, or some
weird sounds being mixed into the audio signal feeding
your stereo's speakers ?
As Dino points out, any audio cabling strung inside the
computer case, can work like an antenna and pick up
emissions from the other hardware. Also, devices that
draw a lot of current from the power supply, can modulate
the power rails, and create audible sounds in the speaker
output by doing so. The motherboard sound chip is usually
fed from a three terminal regulator, but the frequency
response of such regulators may mean that high frequency
noise can leak through them, and when those noises are
aliased down into the audio band, you hear them.
If you go into the mixer control panel for the sound
chip, try muting as many sources as possible in there.
(Mute "CD Player", "Microphone", "Aux", "Line in", "Phone").
Sometimes disabling things in the sound system cleans
some of the noise up. (This trick typically works on
Nforce2 boards.) At least by trying those experiments,
you might get some idea as to where the noise is leaking
in, if the noise source happens to be controllable.
HTH,
