------------------------------------------------------------------------------- You can load the module by typing (as root of course): # kldload %%PREFIX%%/lib/au88x0/snd_au88X0.ko where X is 1, 2 or 3 depending on which Aureal chipset do you have - au8810 (Vortex Advantage), au8820 (Vortex 1) or au8830 (Vortex 2) correspondingly. Please note that you also need to have a `snd_pcm.ko' module either already loaded or placed into appropriate location for modules on your system (default is /modules/ on 4-STABLE and /boot/kernel/ on 5-CURRENT). You can compile and install snd_pcm by doing: # cd /sys/modules/sound/pcm/ && make all install Please also note that module for 4.1-STABLE system is untested, so please use it with caution and if possible please report if it works for you to Alexander Matey . Thanks and enjoy! -Maxim -------------------------------------------------------------------------------
