Picade and audio

A while ago, Peter and I built a RPi based Picade box. It was a lot of fun! We had some issues with sound though, with a lot of static and clicking noises. After some digging, I ended up with the following configurations:

# Enable audio (loads snd_bcm2835)
dtparam=audio=on
overscan_scale=1
# Try to fix sound
disable_audio_dither=1
audio_pwm_mode=2
hdmi_drive=2

I'm not sure exactly which ones are absolutely necessary, but the above works well for us.
