I do not often work on the Linux kernel and I’m also not a Git expert. Therefore getting the latest Linux kernel sources for the Raspberry Pi always takes time. This is a short cheat sheet how to get the latest 3.12 kernel sources:

mkdir linux3.12
cd linux3.12/
git init
git fetch https://github.com/raspberrypi/linux rpi-3.12.y:refs/remotes/origin/rpi-3.12.y
git checkout rpi-3.12.y

Have a look at this nice player by a HiFiBerry DAC owner:

Here is a video showing the device in action:

And some details:

More about this project (in German language) can be found at the Clockworker forum.

Our favorite DIY magazine “Make” features the HiFiBerry DAC and Digi in the current issue.
Quote: “I tested both their DAC and Digi models and was quite impressed at the aural improvement – details are clearer and the audio gains a real sense of space that felt horribly absent when played through the Pi’s built-in output”.

Subscribers of the digital edition can download the current issue already, print customers should receive it in the next days. You’re not a subscriber? You can subscribe online or even buy single issues in digital format. Have a look at makezine.com.
