Setting up usb speakers/mic has the unfortunate feature of assigning usb 'cards' at random during bootup. This will need to be fixed automagically but until that happens:

• cat /proc/asound/cards This will list the 'cards'. This is assuming you are using the adafruint usb mic/speakers recommended by google
• USB-Audio - USB PnP Sound Device - microphone card
• USB-Audio - USB2.0 Device - speaker card Once you have the card numbers you edit this file:
• cp ~/GitProjects/AssAi/asoundrc.template ~/.asoundrc
• vi ~/.asoundrc Change the pcm: hw:<cardno>,1 to have the proper numbers for the mic and speaker.
• HDMI needs hdmi_drive=2 set in /boot/config.txt

Linux uses ALSA for its audio:

• speaker-test *
  • speaker-test -c2
• arecord
  • arecord --format=S16_LE --duration=5 --rate=16k --file-type=raw out.raw
• aplay
  • aplay --format=S16_LE --rate=16k out.raw
• alsamixer (gui) or amixer (command line)
  • amixer -c 2 cset numid=3,name='PCM Playback Volume' 100
• aplay --format=S16_LE --rate=44100 audio3.raw

Assumes you have eth0 (wired) hooked to router with no ethernet connection of it's own
