I have had my acer aspire m3910 for about a month now and recently I hear a hissing and squeaking sound in my headphones... could this be sounds from my computer leaking to my sound card? If so does any one have any ideas why this would have started and how to fix it?

Thanks.

It most certainly is what you've described.
Try moving the card to another pci slot.

Thanks for replies.

Actually my Audio is just High-definition audio support, I am also using a nvidia geforce gt320 video card and it shows 3 or 4 nvidia high definition audios in my device manager.

After a little investigation the hissing and squeaking sounds coincide exactly with the hdd sounds when it gets to whining is when I hear the same sounds in my headphones, I have turned headphones and no hissing squeaking turn them on and it is there, if I take the headphones off I can hear a very similar sound coming from the hdd. I have an Acer Aspire M3910:

Processor

Not sure how to get rid of noise. If I do add an actual sound card can I get rid of the realtek audio... I don't like realtek I never have are there other options for audio support or am I stuck with it?

One other option to making it quieter might be to get a sound barrier case for my hdd.

What about the headphones? I suspect there may be some shielding issues. You say this doesn't occur without the headphones, do you have system speakers? Do you hear anything from the speakers?
What kind of headphones?

As far as the audio goes, the pc should default to a pci sound card if installed but there are options in the BIOS to disable the onboard sound.

Thanks for info.

The same sound comes through speakers as well, the headphones are nexxtech with a mic attached and the speakers are

winex sb 168m very low rate no doubt. On further investigation this problem only occurs when the headphones or speakers are

plugged into the front of computer, also in near proximity with hdd. For now am forced to use rear outlets on computer might try

an hdd sound barrier cover not sure.

Thanks for replies and info!!!

Your welcome. Its obvious the front ports are poorly shielded. It does sound like you should invest in a hard drive silencer:
