New issue by LinArcX on void-packages repository

https://github.com/void-linux/void-packages/issues/42698

Description:
### Is this a new report?

Yes

### System Info

Void 6.1.15_1 x86_64 GenuineIntel uptodate hold rFF

### Package(s) Affected

alsa-utils

### Does a report exist for this bug with the project's home (upstream) and/or another distro?

_No response_

### Expected behaviour

I am using Alsa for sound/audio management on my void machine and i have two monitors:
1. one from my laptop
2. one is external

I can switch between them by changing the device number in `~/.asoundrc` like this:
```
defaults.ctl.card 0;
defaults.pcm.card 0;
defaults.pcm.device 0;
#defaults.pcm.device 3;
```

And every time i came here and uncomment the last line and comment the third line, if i want to use external speaker.

For affecting the change, there is a command:
`alsactl kill rescan`

But it doesn't work for me. any idea?

### Actual behaviour

when I run this command:

`alsactl kill rescan`

It should read `~/.asoundrc` file and affect the changes.

### Steps to reproduce

1. Just install `alsa-utils`

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
}

```
