Good morning!

I made yesterday a fresh installation of Raspian and AlexaPi but i can't make it works, following error:

ALSA INFO AT: http://www.alsa-project.org/db/?f=ff14c276b1d87c116b56c193c3545ba724d37bdd

Your OS (including version) where you are running AlexaPi:

Raspbian Jessie with PIXEL 4.4

**Your hardware platform and model you are running on:**

Raspberry P3

Description of problem:

Audio issue, Alexa service starts but with following error: [6bf004d8] alsa audio output error:...r
Alexa doesn't speaks

Hint: Some lines were ellipsized, use -l to show in full.

System audio works fine because I've checked it with arecord and then aplay.
aplay /usr/share/sounds/alsa/Front_Center.wav

arecord -f S16_LE -r 16000 -D pulse test.wav
aplay -f S16_LE -r 16000 test.wa

Problem-relevant config.yaml entries:

input_device: "pulse"
output: "pulse"
output_device: ""

Hope someone can help and I posted all the relevant and usefull info.
Thank you all!

Hello,
can you copy/paste the output of:
aplay -L
And the full log:

sudo systemctl stop AlexaPi.service
/opt/AlexaPi/src/main.py -d

(you can exit with Ctrl+C)
Are you using VLC or SOX?

Ok @PeterH888 Alsa seems to detect with no problems your devices.
Try this: #242 (comment)

Thanks EmerickH, I'll give that try.

Hi EmerickH, I have removed Raspian Pixel and installed Raspian Lite. Installed Alexapi from git-hub instructions, configured alsa to my usb mic and 3.5 speaker jack and on boot I hear "hello". When I use the wake word "Alexa", Alexa replies with "yes". When I ask a question I get no response but after 8-9 secs I can again use the wake word and Alexa replies with "yes". What am I missing here.
These are the aplay -l and arecord -l

Hello @PeterH888,
what input_device are you using in your config?
Can you copy/paste the output of: arecord -L ?

So you must put input_device: "plughw:CARD=Microphone,DEV=0" in you config file

@PeterH888
Copy link

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

Name of your ALSA microphone/soundcard in arecord -L
input_device: "plughw:CARD=Microphone,DEV=0"

playback_handler: "vlc"

output: "alsa"

output_device: "default"

still gets me no response

This is what I get with: arecord

pi@raspberrypi:~ $ arecord -f S16_LE -r 16000 -D plughw:CARD=Microphone,DEV=0 test.wav
arecord: main:722: audio open error: Device or resource busy

or this

pi@raspberrypi:~ $ arecord -f S16_LE -r 16000 -D "plughw:CARD=Microphone,DEV=0" test.wav
arecord: main:722: audio open error: Device or resource busy

@PeterH888 have you closed the service before?
sudo service AlexaPi stop

not that I can remember
I have used
sudo systemctl stop AlexaPi.service
to stop before degugging

@EmerickH
does the last line here make any sense to you. It appears as if AlsaAudio is not picking up my microphone.
