Re: No sound in precise after kernel upgrade
Adding the suggested module config worked for me too (Dell Studio).
But I see no reason to be happy about it. A simple upgrade of a stable Ubuntu version turns the sound off. This suggests it might be better to not upgrade to the latest stable release but instead take a one-year old one to ensure everything remains working in your working environment after your weekly package updates.
What's Ubuntu's opinion about this? Was this a one-time issue or is current hardware simply too complicated to ensure upgrades are working everywhere, anytime?
