Volume module causes hanging infinitely

After updating ubuntu packages, i3-wm doesn't work anymore. I could track back to i3status.
Calling `i3status` from terminal will output this freezes the terminal.

```sh
$ i3status
{"version":1}
[
```

My simple i3status config:
```sh
general {
output_format = i3bar
colors = true
markup = pango
interval = 5
}

order += "volume master"
order += "tztime local"

volume master {
format = "  %volume "
format_muted = "  muted "
device = "default"
mixer = "Master"
mixer_idx = 0
}

tztime local {
format = "  %a %-d %b  %H:%M "
}
```

If commenting out the `volume master` parts, then it works again.
Maybe because my machine don't have input/output volume devices. But it should not cause this hanging issue on the hold i3-wm.

Also tested with `i3status 2.15` by compilation from source. It has the same issue.
