^^^^^^^^^ seems like this is device is unsupported. ie: although it identifies itself as a sound controller, there is no driver that claims it.

Umm, which kernel version are you using ? Try using a newer kernel to see if your device is supported. If you already are at the latest kernel, i'd say you are out of luck. Your options would be either buy a new sound card or write the driver.
could you paste the relevant section from "lspci -vvv" and mention your kernel version (uname -a) ?

But do exhaust your options with configuring the kernel first!

Cmedia is supported. snd-cmipci is the driver. Unless you are using a 2.4 kernel.
Generally after an installation, the Linux desktop does not produce sound automatically. In the sound 'speaker' icon on the desktop, start the mixer and pull up all the volume controls especially PCM and Headphones. Then close the window and right click on the same speaker icon and click 'Select Master Channel'. This is either PCM or Headphones. This will dynamically control the volume level.
