Let this be a quick one again: my Librewolf browser plays perfectly fine audio
now on any YouTube video.

## Settings in Librewolf

Open <kbd>about:config</kbd> and look for or create `media.cubeb.backend`. This
setting should contain a string value.

```
media.cubeb.backend               sndio
```

I've also tried to set this to `oss` but it works better with `sndio`.

## System wide settings

### Enable sndio daemon in <kbd>rc.conf</kbd>

```conf
sndiod_enable="YES"
```

Eventually run `doas service sndiod start`.

### Settings in <kbd>sysctl.conf</kbd>

```conf
kern.sched.preempt_thresh=224
dev.pcm.0.play.vchanrate=192000
dev.pcm.1.play.vchanrate=192000
hw.snd.latency=7
```
