🅰 Alsa setup

Find your devices

First you must find your input/output devices,

Output device

Type in a terminal:

aplay -L

and search for plughw:CARD=XXXX,DEV=X where XXXX is your device name and X its number.

Input device

Same thing for input device but with this command:

arecord -L

ℹ With some USB mics, you may have to use something like USB PnP Sound Device: Audio (plughw:1,0) instead of plughw:CARD=XXXX,DEV=X

Edit AlexaPi’s config

Locate config

The default AlexaPi’s config emplacement is /etc/opt/AlexaPi/config.yaml or in the same folder as AlexaPi.

🚫 If there’s no config.yaml, create it:

sudo cp -n /etc/opt/AlexaPi/src/config.template.yaml /etc/opt/AlexaPi/config.yaml

Edit config

Now edit it with nano for example:

sudo nano /etc/opt/AlexaPi/config.yaml

and change theses lines with your input and output devices:

  input_device: "plughw:CARD=XXXX,DEV=X"
  output: "alsa"
  output_device: "plughw:CARD=XXXX,DEV=X"

Now save (Ctrl+X - y - Enter - Enter for nano) and start/restart AlexaPi

sudo service alexapi restart
