See also unofficial wiki. Feel free to make additions and contributions.

The online alsa-docs (above) have info on using the .asoundrc file. You can find more in the Unofficial ALSA WIKI and the alsa-lib documentation.

Take a look at the latest alsa-driver/INSTALL file to read information about the newest drivers and their use. If you have questions ask on the mailing lists.

Yes, from our main site - .

Version is available in linux/include/sound/version.h

ALSA library has a copy of kernel header files and it is backwards
compatible with ALSA code 0.9 final (which is also in the 2.6 kernel 
tree). In other words, you can use 1.0 packages without any problems.

or (use BitKeeper):

bk pull


simply copy files from the ALSA's alsa-kernel CVS module to relevant 
locations in the 2.6 kernel tree.
