Hey everyone,

I just installed Ubuntu 7.10 (Fresh install - not an upgrade). It's
running on a Gateway MT3707 Laptop computer.

I can't seem to get the sound working. I tried several of the sound
settings (System -> Preferences -> Sound), including Alsa, OSS, and
ESD. None of which worked.

The output for the sound card from lshw is as follows:
-------------

The soundcard section of the output of "lspci -v" is as follows:
--------------------

I did check alsamixer to make sure nothing is muted. The speakers are
built into the laptop.

Thank you for the help.
