No Mic Support On My Acer Aspire Revo

I installed ubuntu on my acer aspire revo, but it doesn't have microphone support. Do I need to install additional drivers? Something else? Here are screenshots of the current sound settings:

Looks like it can be a bug:
https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/526121
https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/378806

Someone said this:
> After removing pulse audio the microphone works in Skype

You could try removing Pulse Audio. Ref: https://wiki.ubuntu.com/PulseAudio

PulseAudio Removal:
If you decide you no longer like PulseAudio and would like to disable it: Remove the added lines to /etc/asound.conf If /etc/asound.conf did not exist when you installed PulseAudio, you may remove /etc/asound.conf entirely.

After this, you may remove all of the installed PulseAudio packages.

$ sudo apt-get remove pulseaudio

What version of Ubuntu? There are several Acer computers that go under the name Acer One. Which one do you have? I suspect that you will have to change something in the configuration file for the audio.

I don't think I have PulseAudio installed, as there is no "asound.conf" file, only an "esound.conf".  

Any other suggestions?

Are you using squeeze or alsa as your sound manager?

You should be able to seòlect the device "Analog Stereo Duplex" in your Sound Preferences->Hardware tab.

There are two BIOS upgrades specially labeled for linux and/or FreeDos (you'll have to click on the Drivers and Downloads, Desktops, Aspire, then R1600 to get there): http://support.acer.com/drivers_download.aspx
The systemboard has a Realtek HD Audio chip and that still seems problematical; but, here is a link which has drivers: http://ubuntuforums.org/showthread.php?t=557031

Tobias,

How do I determine what sound manager I am using?

TobiasHolmCommented:
In Ubuntu Software Center you can see installed programs. Search for 'alsa' and you can see if it's installed. Alsa is the default sound manager in Ubuntu.

Try this to reinstall the sound:  


$ sudo apt-get remove --purge alsa-base
$ sudo apt-get remove --purge pulseaudio
$ sudo get clean && sudo apt-get autoremove
$ sudo apt-get install alsa-base
$ sudo apt-get install pulseaudio

Open in new window

ops! The code above should be:
$ sudo apt-get remove --purge alsa-base
$ sudo apt-get remove --purge pulseaudio
$ sudo apt-get clean && sudo apt-get autoremove
$ sudo apt-get install alsa-base
$ sudo apt-get install pulseaudio

Open in new window
