I've found a hack to get this working. The file: /var/lib/alsa/asound.state
has two important fields set to false:
name 'HeadsetL Mixer Voice' name 'HeadsetR Mixer AudioR1'
when I manually edited the file and then ran "alsactl restore" I was able to get sound working.
I'm not sure why the default file is generated incorrectly and why I couldn't enable this using the alsamixer GUI
