constant background noise sound after upgrading to ubuntu 12.04

[Accorte]

After the upgrade to Ubuntu 12.04 from 11.10 my laptop constantly plays a soft windlike noise sound through the laptops speakers.
When I set the audio output to silent and turn down the volume to 0 the noise sound changes a little, but continues playing.
When I plug in earphones the laptops speakers stop playing it and the sound gets only played through the earphones, that's my current workaround to get rid of the annoying noise.
Other sounds like music still playback normally, but the noise is always in the background.

I think I've got an Intel HDA sound card build into my laptop (the new audio-settings tool only shows intern audio as it's name).
Before the upgrade there was a second Soundcard in the list, but that one didn't work.
The laptop is a LG R710.

If there are any logs and configuration files I can append to help you please tell me.

I have the same issue. the noise is bearly noticeable at low volume, at higher volumes there is a horrible high frequency "hiss" added ... i tried to hassel with /etc/modprobe.d/alsa-base.conf options + asla force-reload as found in the ubuntu wiki to no avail. back to the original distro alsa-base.conf for now...

cat /proc/asound/card0/codec* | grep Codec
Codec: Realtek ALC889A

i have a ga-ep45-ud3r

looking after my bug:
well, it was'nt one ... use alsamixer to turn down 'frontmic playback' and store these settings with 'sudo alsactl store'
if at all it is a usability bug in gnomes sound thingies inability to control/mute playback of inputs
sound plays nice now as does the precise pangolin...

Thank you very much hatori!
The that worked for me, the only difference is that the device was only called 'mic' and not 'frontmic playback'.

[Mike Guo (hylinux)]

I just do as Hatori did.
it doesn't work for me at all.

anyone have any update about this issue?

Seeing the same thing Laptop HP dm4-1140SA, wind like / train going over track noise when earphones are plugged in.

After audio has stopped playing, about 30 seconds, the background sound stops. Once audio is played again the horrible background noise returns. Muting the microphones doesn't work....
