I am trying to use my Raspberry PI 3 and Digi+ with Amazon's Alexa sample SDK. I was able to get Alexa working without the Digi+ using the built-in sound output of the RPI3 and a USB microphone. After installing the Digi+, I can get music/mpd output to my stereo, but it appears the microphone is disabled.
I am having a struggle with the correct configuration of .asoundrc. The wakeWordAgent (Alexa listener) no longer recognizes the microphone.
Any one have any experience with using the Digi+ and an external USB microphone configuration?
I am using one of the HiFiBerry preconfigured Raspbian SD cards.
