Where to Start
You can Google your way to most software, but there are some great package resources out there. I'm on Red Hat, so I use PlanetCCRMA. The Planet is a project at Stanford's Center for Computer Research in Music and Acoustics, maintained by a knowledgeable guy named Fernando. Not only does Nando maintain Red Hat RPMs of most audio and video applications, drivers, utilities and even custom kernels, he has an extensive guide for installing kernels, ALSA sound drivers and software, as well as for tweaking your machine's performance. I highly recommend reading through the Planet, even if you're not using Red Hat. There are other similar resources for different distributions. Places to start:
