+Like I said in the [previous entry](/post/openbsd-tethering.html) I
+don't like to write _howtos_: the information tend to rot away if not
+carefully updated, and I don't have all that stamina.  Anyway, I felt
+like writing this, and so here we are.
+
+Due to events that are outside the scope of this entry, I moved my
+computer in a place where I cannot comfortably attach a jack to it.
+(I realized this only after the rearrangement, shame on me!)
+
+While any sane person would just have bought a longer jack cable (that
+I should have somewhere anyway) I decided that was the right time to
+test the network capabilities of `sndio`, the audio server of my OS of
+choice.
+
+I have to admit that while at a first glance sending audio over the
+network may seem complicated, I was surprised by how easy it was.
+
+The plan™ was to route all the audio from my OpenBSD workstation to a
+raspberry pi through the LAN.  Why a raspberry?  Because I had one
+spare that was accumulating dust.
+
+So, I installed void linux on the raspberry (OpenBSD should run on the
+raspberries, but for the installation you need to use the serial, and
+I don't have an adapter).  The setup was really quick:
+
+```sh
+# xbps-install sndio
+# xbps-install alsa-utils # for alsamixer
+# echo 'OPTS="-L-"' > /etc/sv/sndiod/conf
+# ln -s /etc/sv/sndiod /var/service/
+```
+
+(the `-L-` is to tell `sndiod` to accept connection from anywhere.)
+
+And for the pi that's all.  (except that I still have to increase the
+volume with `alsamixer` after every boot).  Now, back on the
+workstation I added this to my `.xsession`
+
+```sh
+export AUDIODEVICE=snd@192.168.1.12/0
+```
+
+(You probably want to change the ip address, and only that!  `snd@`
+**IS NOT** a username.  The same goes for the `/0`: it's the device
+number, not some CIDR notation.)
+
+Now all the audio is transparently sent through the network to my pi,
+and from there to my headphones via my (short) jack cable.  Awesome.
+
+That's really all.  Now the bad news: you could have same some time by
+reading the FAQ on the OpenBSD website instead of this post :P
