    This is an hardware limitation. AWE series don't support multiple PCM
    streams.
    So mixing multiple PCM streams must be done in software. Use either esd,
    artsd, ...

    You could imagine a driver based software mixing but :
    - it would make drivers far more complex -> more bug-prone,
    - it may pose performance/feasability problems when your apps need
    accurate timings (Video/audio sync for example).
