!Sound flicking and stuttering in librewolf/firefox

Let this be a quick one again: my Librewolf browser plays perfectly fine audio
now on any YouTube video.
## Settings in Librewolf
Open about:config 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 rc.conf
```conf
sndiod_enable="YES"
```
Eventually run `doas service sndiod start`.
### Settings in sysctl.conf
```conf
kern.sched.preempt_thresh=224
dev.pcm.0.play.vchanrate=192000
dev.pcm.1.play.vchanrate=192000
hw.snd.latency=7
```
