Configure ALSA for Crystal 4237B

While having wireless Internet access is very sweet, I don’t currently have working sound on my laptop (it was also somewhat problematic with SuSE too). I’ve been googing for anwers and not had a lot of luck. I did find that I need to have acpi=off when I boot up or Ubuntu won’t be able to detect the soundcard. Other than that, all I’ve found so far is that I’ll probably have to manually specify all the settings for the soundcard, as detailed in this HOWTO. If this is something that you think you can help me with than you can read some details of my laptop after the jump.

Update [15 May 2005. 7:57 PM -06:00 GMT]: I just realized that I left off some information that could be useful to diagnosing my sound problems. In the Gnome Multimedia Systems Selector, when I choose ALSA as the default output sink and hit the test button; I get this error:
Failed to construct test pipeline for 'ALSA - Advanced Linux Sound Architecture'

I’ve checked and my user is a member of the audio group, so I shouldn’t be having a rights problem.

Additionally, my laptop is a Dell Latitude CPi D300XT, see the complete specs here.

You might also want to read my latest post on this subject, as I actually got the sound to work in that post.
