How, for instance, do I tell aumix where to look?
User space programs don't use ALSA device files directly. They access them via alsa-lib. To do this the programs have to be coded for alsa-lib. If the program has been written for OSS this doesn't work. An example for an ALSA device would be hw:0,0 which means hw (direct access) card 0, device 0. As there is no intermediating layer (i.e. for samplerate conversion) you normally don't want to do this (except you know exactly what you do). The 'default' device should do fine. How exactly you configure the ALSA device depends on the application. Low level ALSA tools, e.g. aplay have the '-D' option. For ALSA mixing you should try alsamixer (curses based) or amixer (low level CLI). There are also several GUI Frontends out there, e.g. gnome-alsamixer. Skimming over aumix, I suspect that it does not have native ALSA support. The TODO file states "add support for ALSA" and this is from 2002!
