What is the latest version of ALSA?
Latest released version is 0.4.1. This version requires Linux kernel 2.2.3+ Linux 2.0.x kernels are no longer supported. This said, most of the real action goes on in the daily CVS updates. Newer features and bugfixes show up in the CVS long before the official point-release tarballs, and the CVS versions tend to be very usable. See 2.5 below for information on how to get CVS snapshots of ALSA.
