I am trying to use a microphone with a Raspberry Pi 3 Model B running Raspbian Wheezy.

I have a use audio card shown here: http://www.currys.co.uk/gbuk/computing-accessories/components-upgrades/sound-cards/dynamode-usb-sound7-7-1-channel-usb-sound-card-17771622-pdt.html

The mic I am using is a headset with twin 3.5mm jacks (mic and headphone).

The output of aplay -l:

**** List of PLAYBACK Hardware Devices ****
card 0: ALSA [bcm2835 ALSA], device 0: bcm2835 ALSA [bcm2835 ALSA]
  Subdevices: 8/8

  Subdevice #0: subdevice #0
card 1: Device [USB Audio Device], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

I attempt to record using the following command:

arecord -D plughw:1,0 -f cd test.wav

I get absolutely no sound on playback.

If possible I would like to use HDMI as audio out and the usb card purely for audio input.

I followed the steps discussed here http://www.linuxcircle.com/2013/05/08/raspberry-pi-microphone-setup-with-usb-sound-card/ but with no change.

If I allow the card to become the default card amixer will show:

Which suggests the mic is there?

also running

speaker-test -t wav -c 1 -D hw:1

comes out the HDMI,

speaker-test -t wav -c 1 -D hw:0

does not come out the headset. I have yet to hear audio our the headset.
