Well, in this particular case, let's just see what the generic user out there probably has. In quite a lot of cases it's some SoundBlaster Audigy2 or X-Fi variant which both have somewhat extensive signal processing capabilities (or that's what I've understood). Or you could take ancient Aureal's Vortex2 as an example. Or also rather common CMI8738 (not sure about this one). Current Linux support for these devices is limited to PCM playback/recording and possibly bare MIDI. Currently the thing we really are missing on Linux is HAL support for something like OpenAL w/ EFX (or some DirectSound3D-for-Linux type thing). Having this is somewhat crucial for game development. This is also something OpenSL ES (http://www.khronos.org/opensles/) is trying to address on embedded area. - Jussi
