conexant ac link audio s hp notebooks

I see a lot of people have the same issue.
I have an HP Pavilion ze5375us Notebook and can not get the "Audio" to work with Vista. The device manger has the ! "Conexant AC-Link Audio". I've tried every possibly way to install the driver. I tried every driver that was for the same chipset. No good. Still No Audio. I tried the Audio64a.zip and at a command prompt ran "Bcdedit.exe -set nointegritychecks ON" and restarted the computer.. Still No Audio.
I contacted HP and they are "very aware" of the problem are will be posting a driver as soon as possible. I hope they don't drag their feet. I would be great if the Vista Team would jump in and get us HP Pavilion users some Audio drivers.
Any ideas or work arounds???
Thanks
