Browse Source 
sndio is the native API used by OpenBSD, although it has been ported to
other *BSD's and Linux (packages for Ubuntu, Debian, Void, Arch, etc.).

Sets the count of the buffers.
``-audiodev sndio,id=id[,prop[=value][,...]]``
Creates a backend using SNDIO. This backend is available on
OpenBSD and most other Unix-like systems.
Sndio specific options are:
``in|out.dev=device``
Specify the sndio device to use for input and/or output. Default
is ``default``.
``in|out.latency=usecs``
Sets the desired period length in microseconds.
``-audiodev spice,id=id[,prop[=value][,...]]``
Creates a backend that sends audio through SPICE. This backend
requires ``-spice`` and automatically selected in that case, so
