With one kernel sources, you can make several kernels. The best is to begin with the in-kernel alsa driver. Make and install the kernel and the modules. Next, move the .config file to a safe place. make mrproper, put back the .config file, make oldconfig, make menuconfig. Here, change the kernel extra_string, this will create a new directory in /lib/modules when installing the modules. Keep "<M> Sound card support" but remove all the other sound modules (the whole alsa). Make and install the kernel and the modules. Install the alsa driver from the alsa sources. This will result in 2 different kernels with their modules in 2 different directories in /lib/modules. Dominique > The other question I would like to make is a bit more 'exotic'...
