The Word of Chaos

To my surprise, I once again had the “no-sound” issue when I upgraded from Ubuntu 8.04 to Ubuntu 8.10.  The same fix that re-enabled my sound in Ubuntu 8.04 also fixed my laptop in Ubuntu 8.10

The symptoms are:

• alsamixer only presents controls for the Master volume.
• Sound through the headphones work, but speakers do not.

The solution is as follows:

1. Make a backup copy of /etc/modprobe.d/alsa_base, if you wish.
   ex: sudo cp /etc/modprobe.d/alsa-base /etc/modprobe.d/alsa-base.old
2. Open /etc/modprobe.d/alsa-base in your favorite text editor.
   ex: sudo nano /etc/modprobe.d/alsa-base
3. Add the following line to the end of the file:
   options snd-hda-intel enable=1 index=0 model=basic
4. Save the changes to the file and reboot.

I hope this helps someone who’s frustrated with this particular issue.
