I am using an alsa driver, but would like to view the volume from the Master channel on card #2. I'm not sure how to get that in i3status. I can only display the default card with:

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

But this is not the correct card that is hooked to my speakers. I need card #2. When I try to put in mixer = "Master" and mixer_idx=2, I get errors like:

i3status: ALSA: Cannot find mixer Master (index 2)

How can I get the volume on card #2 channel Master in .i3status?

My .asoundrc is:

pcm.!default {
   type plug
   slave.pcm "dmixer"
}

pcm.dmixer {
  type dmix
  ipc_key 1024
  slave {
    pcm "hw:2,0"
    period_time 0
    period_size 1024
    buffer_size 4096
    rate 44100
  }
  bindings {
    0 0
    1 1
  }
}

ctl.dmixer {
  type hw
  card 2
  device 0
}

And here's the output of aplay -l:
