Volume module causes hanging infinitely

[iiey]

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.

$ i3status
{"version":1}
[

My simple i3status config:

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.
