Acer Aspire One AO722 Microphone Not Working Ubuntu 12.04LTS

Acer Aspire One AO722 Microphone not working. I have a good sound in speakers.

So far I have tried:-
1. I have downloaded this and installed but it gives an error ask me whether you want to report this, I choose yes, http://people.canonical.com/~diwic/t...tg_0.1_all.deb
(I uninstalled it)

2. I am started with this

# sudo add-apt-repository ppa:ubuntu-audio-dev/ppa
# sudo apt-get update
# sudo apt-get install linux-alsa-driver-modules-$(uname -r)
# sudo apt-get install pavucontrol

But it gives an error "Unable to locate package linux-alsa-driver-modules-3.2.0.24-generic-pae" "Coudn't find any package by regex 'linux-alsa-driver-modules-3.2.0-24-generic-pae"

Taken from the Acer 522/722 wiki

* Open a terminal window and run "alsamixer"
* press F6 and choose "1 HDA ATI SB" as a sound card to configure by pressing Enter
* to see the mic-related sliders, press F5 and move the cursor keys to the right, only the outermost three sliders need to be set to a level of 56 by pressing the Up key
* then, by pressing the "c" key on each of the three sliders, the volume level of each right channel needs to be put to 0
* finally, quit alsamixer by pressing ESC.

Comments:
1) I set mic boost and capture to 100 and I get no hum. Muting the right channel is key.
2) When everything is set, execute

sudo alsactl store

3) The settings need to be restored at every boot. Add this command as a startup application

alsactl restore

Cheers!

that worked for me on my 722, but in testing with soundrecorder the background hum is very loud! are these settings right? Otherwise, sound playback works fine.
tried raising and lowering the volumes of ike boost and capture to no avail, there is always a loud hum. When I plug in an external mike it's still the same hum.

[brallan]

uff in the community wiki it says that there is no way to get rid of the hum, and indeed, even with an external mike I still have hum. What a bummer. LewisTM, do you have a 522 or a 722?

[Jazqas]

Not sure if this a real solution, but I installed qasmixer and played with the settings (mixer device : hw and mic boost) until it sounded better.
Hope this helps.

I have a 722 running Xubuntu 12.04
No difference except I have beep set at 100%.
I also have the /etc/asound.conf specified here.
Tested on Skype and Sound Recorder and both record and play back fine.
