Ready for whom? The physical device?

Just in case you guys aren't familiar with it, the a52 plugin is not like the
pulse plugin, which routes from alsa to pulse. Instead, basically it substitute
what pulse usually grab.

So usually it's like:
pulse -> iec958
and now it become:
pulse -> (plug:)a52 -> iec958

FWIW, this is mainly useful for S/PDIF only, where multichannel PCM is not
possible.

So this:
pulse(down-mixed stereo / passthrough'd ac3) -> iec958
become this:
pulse(6-ch pcm) -> a52(encoded ac3) -> iec958
