+sndio on Linux works on top of ALSA (or OSS, if THAT is what you have).
+
+Before you start using sndio, make sure to disable all other sound servers,
+these include PulseAudio, PipeWire, Jack.
+
+Default slackware installation ships with PulseAudio over ALSA, so you have to
+disable PulseAudio. To disable PulseAudio, run the following lines as root:
+
+```
+# Disable pulseaudio.desktop:
+if ! grep -q "^Hidden=true$" /etc/xdg/autostart/pulseaudio.desktop ; then
+  echo "Hidden=true" >> /etc/xdg/autostart/pulseaudio.desktop
+fi
+
+# Edit /etc/pulse/client.conf to disable autospawn:
+sed -i "s/autospawn = yes/autospawn = no/g" /etc/pulse/client.conf
+sed -i "s/allow-autospawn-for-root = yes/allow-autospawn-for-root = no/g" /etc/pulse/client.conf
+```
+
+Save the following as '~/.asoundrc':
+
+```
+# See https://www.alsa-project.org/wiki/Asoundrc for more details.
+# Set default sound card to use.
+pcm.!default {
+	type hw
+	card 0
+}
+
+# Set default sound cards to control via alsamixer.
+ctl.!default {
+	type hw
+	card 0
+}
+```
+
+To start sndiod at boot, append the following snippet to '/etc/rc.d/rc.local':
+
+```
+if [ -x /etc/rc.d/rc.libvirt ]; then
+  /etc/rc.d/rc.libvirt start
+fi
+```
+
+And make sure that file is executable.
