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
|
|
|
|
|
```
|
