For RedHat Linux's pre-compiled kernels these + configuration files can be found in + <filename>/usr/src/linux/configs</filename> + After you've located the correct config file for your kernel, + you need to copy it to <filename>/usr/src/linux/.config</filename> + For example, when you run the 2.4.18-i686 kernel do : + <programlisting> + cp /usr/src/linux/configs/kernel-2.4.18-i686.config /usr/src/linux/.config + </programlisting> + Make sure that the emu10k1 module that is currently installed is + not loaded. To unload the modules : + <programlisting> + /sbin/modprobe -rv emu10k1.o ac97_codec.o + </programlisting> + + If this mentions that the device is busy, some program is + using the driver. Some example could be a mixer application + or sound daemon like artsd. You'll need to close down the + applications before continuing. + At success it should print something like : + <programlisting> + # delete emu10k1 + # delete ac97_codec + # delete soundcore + </programlisting> + Run make in the directory where you unpacked the driver and follow the + instructions printed at the end of each step. + The last step should be: + <programlisting> + make install-tools + </programlisting> + + As the README of the driver package mentions the SPDIF AC3 + output doesn't work by default.
