I tried to install with the current changes in head, wasted a lot of time trying to fix an asound.conf that would get the mic working, never happened. Then I decided to install pulseaudio...and it works a treat. It just works!

---

/etc/asound.conf

---

Set pulseaudio as the default output plugin

pcm.!default { type pulse hint { show on description "Playback/recording through the PulseAudio sound server" } }

ctl.!default { type pulse }

---

Changes to .bashrc

Note that if pulseaudio is used aplay can be changed to paplay in /etc/mycroft/mycroft.conf
