Dear Maintainer,

Starting in 5.0.1-1, you've disabled sndio support, with the rationale that
OpenAL will autodetect sndio anyway. While true, the user experience is
downgraded; OpenAL will always use my computer's microphone even if I've started
sndiod with "-m play,mon", meaning it will only use the monitor of my speakers
as my audio input. This sucks when I want to do a screen record with sndio.

Please consider enabling sndio support again. It's just a single build-time
dependency anyway; it's not like we're forcing the user to install libsndio just
to install the binary package.

Thanks
