Hi, Actually, it is quite simple. Alsa sound drivers are kernel modules. Therefore, when you recompile the kernel, you normally have to recompile the alsa modules as well. When you install a SuSE kernel package, k_*.rpm, the alsa modules are included. However, the sources are not part of the kernel sources. To rebuild the alsa modules, I normally proceed as follows: 1) install the alsa source package: rpm -i alsa-<version>.src.rpm note: This package is missing in SuSE 7.3. You can download it from ftp://ftp.suse.com/pub/people/tiwai/7.3-src 2) rebuild the alsa packages: cd /usr/src/packages/SPECS rpm -ba alsa.spec 3) install the alsa module sources: cd /usr/src/packages/RPMS/i386 rpm -Uvh km_alsa-<version>.i386.rpm 4) build the alsa modules cd /usr/src/kernel-modules/alsa-driver-<version> make -f Makefile.module 5) install the alsa modules make -f Makefile.module install That should be it, give or take the occasional typo. After a depmod -a all snd* dependencies should be resolved. You shouldn't have to change your modules.conf at all. Regards, Tim
