I have exactly the same scenario as the person that posted this
link. The only difference with me is that I postponed my Ubuntu
upgrade to 8.04 until the time where the version I was running was clearly no longer
I'm not a Linux kernel expert, I just an ordinary laptop user, so
I'd rather not spend countless hours tweaking my system in hopes that
I might get lucky with a non-standard configuration.
I hope I don't sound too negative, I'm become a little frustrated.
Isn't there a way to get the proprietary drivers that DELL bundled
with its Ubuntu laptops? Has Dell produced any non-vanilla Ubuntu upgrade CDs?
Not sure what special magic they've packaged into them but I think they should be bootable live CDs just like normal Ubuntu CDs so you could boot from the CD and see if your sound card works before installing it.
