Comment:
It wasn't a bug. I should just run `sudo alsactl init` before restarting the Alsa service.

For anyone interested I wrote these two functions that make life more easier:

```
internal_speaker () {
  sd "#defaults.pcm.device 0;" "defaults.pcm.device 0;" ~/.asoundrc
  sd "defaults.pcm.device 3;" "#defaults.pcm.device 3;" ~/.asoundrc

  sudo alsactl init
  sudo sv restart alsa
}

external_speaker () {
  sd "defaults.pcm.device 0;" "#defaults.pcm.device 0;" ~/.asoundrc
  sd "#defaults.pcm.device 3;" "defaults.pcm.device 3;" ~/.asoundrc

  sudo alsactl init
  sudo sv restart alsa
}

```
