Problem Description: notebook models: HP 6530S, integrated sound card chip for the AD1984A,
After the installation of Ubuntu 8.10, headphones had plenty of sound output, but no built-in speakers sound output.
In Terminal, type:
sudo gedit / etc / modprobe.d / alsa-base
The last line by adding:
options snd-hda-intel model = laptop
