ubuntu netbook edition 10.04 - no duplex audio

I'm new to Linux but I wanted something that would outperform Windows on my netbook. I've got an Acer Aspire One AOA-150. I installed Ubuntu Netbook Edition 10.04 and it's great! The only problem I have is that I use Skype quite often and Ubuntu is not allowing duplex audio. Meaning I can't play sound and input sound at the same time which makes Skype useless.

Does anyone know how to enable duplex audio? I tried installing the Realtek HD Audio Codecs per Realtek's instructions for ubuntu but that didn't work. I ended up using the Alsa upgrade script from the ubuntu forums to get audio working again but with no duplexing. Please heeeelllp

Now, you don't have to be too gentle with me, I'm a computer guy and I learn fast, but go easy

Thanks!

I followed the same instructions that are providing Irishhhhh (foundend in some other ubuntu forum) but the fact is that it worked perfect, now I can use without a problem skype with My AOA110.

but I have a Sony Vaio I followed same procedure without success, weird stuff. :shock:

But once again this method worked for Aspire One.

 

irishhhhh's instructions worked perfectly. Thank you!

 

Over here I prefer to avoid PulseAudio (had it, then purged it), so I tried a similar trick.
Alsamixer will do well enough--run alsamixer, tab to the proper view, arrow over, press "C" until the right is muted.
arecord -d 20 -t wav test.wav produces a very staticky recording. Turned down the left channel a little, it sounds better.
