I didn't go the mercurial way, but with help from Fernando at planetccrma, and folks on the alsa user list, it proved to be an unbelievably easy procedure. Details below for anyone that might read this thread. Using the latest installed kernel, which also has the kernel-headers package for it installed. Install the kernel-devel package for the same kernel. Download the latest development version of the alsa driver from: http://alsa-project.org cd to where you put the downloaded alsa driver, then as user. ./configure followed by, if configure goes ok. make su to root, and then. make install Make install also runs depmod -a so there should be no need to run it again. Reboot into the same kernel, and check if you now have the new alsa driver with. cat /proc/asound/version This procedure above assumes that you didn't already have kernel-devel installed for a previous kernel. Untried by me, but if you have more than one kernel-devel package installed, you need to pass an option to configure. ./configure --with-kernel=<kernel-directory> Where <kernel-directory> is the name of the directory for the kernel that you want to upgrade the driver to in /usr/src/kernels (I don't think you have to specify the full path, as configure should look in /usr/src/kernels anyway). And as has been said, the same procedure will have to be repeated for each newer kernel installed, along with it's kernel-headers, and you will have to install the kernel-devel package for your latest kernel before proceeding. I hope I havn't missed anything, but it's worth having a read at the INSTALL file in the driver tarball. For example on earlier versions of FC, particularly if you have planetccrma installed, there is an alsa start script, and you can set configure options to avoid this being replaced. All the best, and thanks to all who have helped. Nigel.
