no sound on hp pavilion dv7 laptop

[Stem]

Binary package hint: firefox-3.0

I have installed edubuntu 9.04 alongside windows vista on my hp pavilion dv7 laptop. But, since installation there has been no sound except at start up when i get a repeated drumming going over and over that slowly fades out. I believe it is the sound that ubuntu usually starts up with, but it just continues and is somewhat distorted. After this sound fades there is no sound through the speakers. I have tried playing music with Amarok and Rhythmbox Music Player. The sound card on this pc is an IDT High Definition Audio. I think the issue is that it requires special drivers which aren't available on ubuntu, or I haven't found them yet.
Any advice would be great, cheers.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately we can't fix it without more information.

Could you please run:
apport-collect -p alsa-base 376167

I just performed the above requested command, but it looks like apport crashed before it finished (see terminal output below). I also have an HP dv7 notebook. Ubuntu 9.04 has been installed via Wubi and I have no audio as described in Stem's original report.

Here is my terminal output:

This looks like a duplicate of #326896. The user who logged #326896 provided a solution in the bug description which also worked for me.
