I have a relatively new Intel "Ultrabook", the HP Envy Spectre XT. It has the IDT 92HD99 sound card. Support for this was added to ALSA 1.0.25 based on this changelog:

http://www.alsa-project.org/main/index.php?title=Changes_v1.0.24_v1.0.25&action=edit

However the ALSA driver version in Ubuntu 12.04 is 1.0.24. Can someone explain how to update the ALSA driver to 1.0.25? The alsa-base package says it's using a package version 1.0.25-dfsg-0ubuntu1.

Here is my ALSA version info:

!!ALSA Version !!------------

Driver version: 1.0.24 Library version: 1.0.25 Utilities version: 1.0.25

I think I need to get that "Driver version" up to 1.0.25 to get support for my hardware. Any help? Thanks.

A solution will be to use the ppa ppa:ubuntu-audio-dev/ppa.
It description says

This PPA will be used to provide testing versions of packages for supported Ubuntu releases.

It contains ALSA 1.0.25 driver package for precise(12.04).
N.B: I haven't tested it, so please be careful.

Yes, Ubuntu precise LTS is having the ALSA version of 1.0.24. You can look at the below link, where the upgrade script has been attached. I have tried on the AMD's new SI products and it worked well.
