Tmbinc about: 24C3 Presentation, 360 Linux Sound Driver

January 3rd, 2008, 18:49 Posted By: wraggster

The 24c3 is over now, and we really had a lot of fun. We brought 6 of our Xboxes, which allowed us to grab attention from quite a lot of people in the hackcenter .



Axel, who already wrote the free60 X11 driver using a revolutionary (ok, let's say: "interesting") remote development method, started, together with Tom, hacking on a Xbox360 linux sound driver. The bad thing was that they had nothing more than a really short braindump of what I so far found out on the sound hardware (and that was really not much more than a list of registers associated with the sound). But some hours later, they had a first result: No sound, as we didn't brought speakers with us, but we just hooked up a multimeter to the sound port, and whenever they would "trigger" the sound driver, the multimeter showed some activity!

Luckily it was (almost) daytime, so we just bought speakers (and more DVDs for Ben), and voilÃ*: sound! It was something uncontrollable, but some time later we had some code which we estimated to output a plain sine wave. But somehow we screwed it up, and the output was an interesting piece of music, just not a simple sine wave. Ilinuxp. On the other hand, it's a mystery for me how they could bring the hardware to output anything at all! Thanks a lot, you two! I will soon provide Axel a skype link so you can continue developing remotely
