After Alexa starts, alsaaudio.ALSAAudioError: Input/output error

sikkz commented 7 years ago

Hello, I receive the "Hello" from Alexa and the green LED flashes 3 times. But after pushing (and holding) the button, I only receive this output:

Checking Internet Connection Connection OK Traceback (most recent call last): File "main.py", line 156, in start() File "main.py", line 130, in start l, data = inp.read() alsaaudio.ALSAAudioError: Input/output error

I googled the error, and checked the Issues page here, but can't find a solution. I am using a Raspberry Pi 3 and a Webcam with integrated microphone. If anybody has a solution, please try to explain it well, because I am just starting to learn programming.

Thanks for your help in advance!

You are not calling correctly the microphone, check the solution here it may work for you: https://github.com/sammachin/AlexaPi/issues/135

First, thank you for your reply! I ran the arecord -L command. Because of the results, I changed: "plughw:1 to plughw:Camera=Device,DEV=0" But still I only receive the "hello" and three green flashes. When I press the button, say something, and release it, nothing happens. After 5secs or something, the main.py closes itself.

The alexa.log file says:

Starting Alexa...
pysthon can't open file '/root/AlexaPi/main.py': [Errno 2] No such file or directory

EDIT: I googled this error, and changed the directory in the initd_alexa.sh file from "/root/AlexaPi/" to "/home/pi/Downlaods/AlexaPi/main.py"

Still doesn't work. May I have to change the directory in another file? Or should I move the whole AlexaPi folder from downloads to root? If yes, how can I move it? Sorry if this post is kinda unorganised, I am actually trying to solve the problem, and am updating this post everytime I get another hint.

Heres the arecord -L output:

Can you try the new upstream (https://github.com/alexa-pi/AlexaPi)? The installation over there is more robust and it might be therefore easier to get it to work. Just follow the installation guide. Thanks!

renekliment commented 7 years ago

This project is now deprecated in favor of the new AlexaPi (https://github.com/alexa-pi/AlexaPi) which has all the features of this project and much more, such as:

support for a wide range of devices and platforms (Raspberry Pi, CHIP, Orange Pi, desktops, Magic Mirror and others)
voice activation (great PocketSphinx support and snowboy support soon to be released)
much more robust installation and configuration
better security
Arch Linux support
awesome documentation
and much, much more! You get it - it's just awesome.

Please switch over to the new project and if your issue persists there, file an issue in the new repo's issue tracker. Thank you.
