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?
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:
Model : Intel(R) Core(TM) i7 CPU 870 @ 2.93GHz
Speed : 3GHz
Total Memory : 4GB DIMM DDR3
Model : Acer Clarksfield/Lynnfield DMI
Front Side Bus Speed : 2x 2.4GHz (4.79GHz)
Video Adapter : NVIDIA GeForce GT 320 (48 SM4.1 1.3GHz, 1GB DDR3, PCIe 2.00 x16)
Windows System : Microsoft Windows 7 Home 6.01.7601 (Service Pack 1)
Platform Compliance : x64
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?
