By way of clarifying the intent here, this library seems to exist to funnel
arbitary async transactions through the alsa kernel module.  This covers the
case whereby the streaming component (in the kernel) influences the way
these commands are carried out, or when an ARM handler (which by definition
must be a centralised resource) forms an integral part of the data exchange. 
Is this more or less correct?
