Hello Chris, very good sum up, yes my esp8266 is connected to wifi, and
using UDP is trying to send "almost near real time" at least the lag is not
very perceived, now, the remote server is not on my local network, is a
linode server, and I am trying to use snowboy kitt, which relies on pyaudio
and is pyaudio the one which fails if a sound card is not present, I
created a dummy sound card but I still cannot manage to make mi virtual
microphone the default one
