I was thinking more about using many oss apps at the same time. What's wrong with allowing same soundcard opened by multiple programs and the streams from them mixed (in sw or hw) IN alsa? This way you could use many oss/alsa apps directly without soundservers or other extra layers.. If I would be interested implementing something like this, where should I start looking at the code..?
