It should work for you, provided you've freshly installed UNR 9.04.
First, you will need to use this code in terminal.
wget ftp://ftp.alsa-project.org/pub/driver/alsa-driver-1.0.20.tar.bz2
tar xjvf alsa-driver-1.0.20.tar.bz2
cd alsa-driver-1.0.20
sudo apt-get install build-essential module-assistant
sudo m-a update
sudo m-a prepare
./configure --with-cards=all
make
sudo make installSome of the above code may get cut off by the sidebar of this website.If so, the first line reads :
wget ftp://ftp.alsa-project.org/pub/driver/alsa-driver-1.0.20.tar.bz2
The above code should take about 20 minutes to do... so have patience with the make commands.
Credit goes to user : Micdhack on Ubuntuforums.org for the code segment.
Don't bother trying to check what it did just yet, you will want to restart first.
After restarting, go to Preferences > Sound.
Change the sound capture option to : OSS (Open Sound System)
Close the sound options.
Now open your Volume Control settings by clicking on the speaker icon top right. Click Volume Control.
In the Device drop-down, select [Realtek ALC272 (OSS Mixer)]
Click on the Preferences button.
Place a check-mark next to In-Gain.
Close this small window.
Slide the newly available In-Gain slider to the top.
Close Volume Control.
Open sound recorder, hit record, viola! The interference from inside the room can't be eliminated as far as I can tell, the mic is a tiny mic and is very sensitive to higher frequency sounds.
You will also likely be wanting to make videos using Cheeze video recorder. This will also work, but first thing is first, change the resolution (edit > preferences) of the recording to a lower setting, the video will be incredibly choppy otherwise.
You will likely want to be using a flashed based video chat on the internet some time in the future if you're like me and enjoy contact with the world. (Adobe Flash is my recommendation if you haven't already installed flash.)
You may have noticed your camera doesnt appear, instead, you have a black screen. That's because flash on linux doesn't have the ability to ask you permission to use your webcam... I know, complain to Adobe, it's not the Ubuntu communities fault.
If you right click on the Flash Applet and select settings, you can always allow the website access to your webcam.
Alternatively, if you can't access settings from that applet (it happens), go to http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager06.html
Provided you have been to the video chat website, you can select it from that list, and put the dot in Allways Allow.
Once this is done, you should be able to use that flash based video chat website.
If you weren't using Adobe Flash, and you've noticed all videos play incredibly badly, you can uninstall SWFDEC or GNASH through synaptic package manager, and then go to youtube or another flash based site, and select Adobe instead when prompted to install a flash plugin this time.
Again, this is for the Aspire 1 D150, with Ubuntu Netbook Remix 9.04 freshly installed.
