I recently upgraded to the latest version of Ubuntu, which is currently version 12.04. Version 12.10 is just a little over than a month away from being released. With my Ubuntu 12.04 install, I was experiencing some crashing issues with the Unity desktop which drove me nuts. I ended up taking some extreme measures.
I went and installed Xubuntu instead of Ubuntu. Xubuntu uses the Xfce desktop interface. It’s much simpler and quite stable, except for the sound. Why can’t I get a problem-free distro for once. The default PulseAudio audio driver in Xubuntu was stuttering, especially when playing Youtube videos. So, I ended up removing the Pulseaudio and installing Alsa instead.
So, here are the steps I took to get my sound working.
$ sudo apt-get remove --purge alsa-base pulseaudio
$ sudo apt-get install alsa
I also had to edit the /etc/modprobe.d/alsa-base.conf file. Add this line at the end of the file.
options snd-hda-intel model=generic
Save and reboot.
