how to reinstall audio driver?

[pearlygate]

Hi,
my audio does not work in ubuntu. I just replaced my mobo to asus m3a78. I used gigabyte mobo before and gigabyte use realtek chipset whereas asus uses VIA chipset I think.

Is there a way to reconfigure the audio, I bet there's a driver conflict somewhere but if I can restart the audio configuration process (without reformatting and re-installing ubuntu), ubuntu will "know" which driver to use automatically.

Can anyone help?

Thank you

paste the output of these commands from the terminal

aplay -l && arecord -l

lspci -vvv

lsmod

this should give a better insight as to what is going on here.

The best thing to do would be to remove alsa and reinstall it. The same thing happened to me when I switched mobos and this fixed it.

(1) Remove the ALSA packages

sudo apt-get --purge remove linux-sound-base alsa-base alsa-utils

(2) Reinstall the same packages

sudo apt-get install linux-sound-base alsa-base alsa-utils

Packages gdm and ubuntu-desktop are also removed in this process if you are using Gnome. They need to be reinstalled:

sudo apt-get install gdm ubuntu-desktop

If you are using xubuntu this will also happen to you

sudo apt-get install gdm xubuntu-desktop

(3) Reboot.

Are you running ubuntustudio/jack on your aspire one?
I have an aspire one and am thinking of making it a portable ubuntustudio after jaunty release.

oh yes and it runs very smooth, other than the odd vst crashing lmms ardour and rosegarden. when an app crashes i need to reload pulseaudio (as in your tut) .. but it is definately a good notepad for ubuntu-studio..... i also upgraded the ram to 1.5gb(this is the max capable) myself.... ram cost £12 on ebay. .. i have uploaded a few basic demos on youtube some done on the aa1 ,so you could always look at them...... the url is on my profile(i think)
