7 years ago If you want to run it under a desktop OS, you have to set up PulseAudio in system-wide mode. Checkout out the wiki at the right repo. This doesn't concern this repo, closing.
When running alexapi as a service, I can hear the audio and her responses, but it is not picking up my voice.
Checking the status gave me this:

So I stopped the service and ran AlexaPi in debug mode from command line, and to my surprise, everything works fine. I can talk to alexa and she replies back no problem. I have no idea what the problem could be as I'm a beginner at dealing with audio in linux.
I set the audio input and output in the config.yaml file.
sound:input_device: "plughw:CARD=Device,DEV=0"output:output_device: "plughw:CARD=ALSA,DEV=0"This is the output from arecord -L:
