JACK is the only process that opens a ALSA handle referring to the
sound card, either as hw or as plug PCM. AFAIK, it is what is done now,
if you run only JACKified applications. My proposal is to extend this
so that you can run ALSA and OSS applications while staying in this
scheme.

But it seems that this is not acceptable, if I read correctly previous
discussions on this list. How can we overcome this ?
