This is an hardware limitation. AWE series don't support multiple PCM
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).
