Noisy sound card from Microphone input

Hi Hardware experts,

I have a problem with noise from the sound card Microphone input.  

I have had the sound card for a couple of years but this is the first time I have tried to record anything. When I mute the Microphone on the Windows Volume Control, the noise goes away. When I unmute the Microphone the noise is there, regardless of whether a Microphone is plugged in or not. When I record, I can hear recorded audio but it is at a very low level compared to the noise.

I have also tried using the Line input. I do not get any noise from this input. However when I record and then play it back the sound is only on the left speaker.

I have upgraded drivers and this has not helped.

Any suggestions on how I can fix this problem. Or is it time for a new sound card?

Your advice is greatly appreciated.

Regds,
Nick

Sounds like a new card might be the best option.

is it a humming noise,?

A microphone port is usually slightly amplified, and it sounds to me that something might be wrong, since you have constantly noise, and the real input doesn't get amplified.
the fact taht the line-in only gives left-channel indicates the same problem to me.

First, try to do a visual check of the soundboard, and/or then try to reseat it, this sometimes does wonders.

Hi maduropa,

The noise is more of a crackly noise with a periodic crackle that is louder than the rest. The noise is also affected by me simply moving the mouse around and changing between applications.

I did a visual check but could not see anything obvious - not sure what to look for anyway. Reseating did not help...

Regds,
Nick

I was thinking about a bulging elektrolyte condensator (or is capacitator), or a burn mark on the card.

crackling sound also when you move the mouse,?

I might have heard such noise before,
I experience that noise on an older laptop, Compaq E500 with a pcmcia wireless card. Since that card is connected I hear a crackling noise almost like ticking, and it speeds up when I move the mouse. Silencing the audio doesn't help. Maybe another part in your computer is somehow interfering with the sound-card.
If that would be it, then replacing wouldn't do the trick,
can you test the card in another computer, and vice versa ?

Is there anything in the hardware panel that is mentioning a conflict, ?
