@michael_klatt sorry about that, I edited the post.

@j.e.f.f I found a solution. It seems that the font-awesome style sheet is not being loaded by default, so the microphone icon does not show.

I edited the index.html file located at the root folder of the MagicMirror installation, and added the following line:

< !-- custom.css is loaded by the loader.js to make sure it's loaded after the module css files. -->
< link rel="stylesheet" type="text/css" href="vendor/node_modules/font-awesome/css/font-awesome.min.css" >

I added a space between the < so it could appear here, apparently the editor won’t allow me to paste these kind of lines directly.

Hope this helps.

@michael24h did you ever get the mic to show up? Same problem here.
Thanks!

Hi @j-e-f-f ! Thanks a lot for your response. I tried adding the “classes” line, but still nothing shown in the mirror interface. Alexa responds, but it would be great to see the status in the Mirror. Really weird.

Have a great day.

@romain quick question, I’ve noticed that Alexa takes a few seconds to answer, sometimes around 20 seconds. Does this happen to you as well? Could it be a slow internet connection. Thanks again!

@romain finally got it working by replacing myTest with default as you indicated. Than you so very much!! One short glitch though, sometimes Alexa’s phrases can not be heard completely. For example, at boot time I can hear “o” instead of “hello”. Same happens when talking to her.

But it is working!! Now time to test MMM-AlexaPi

Thanks again @romain

@romain hi again!!

I have done some progress. I followed your instructions, created the asound.conf file and setup myTest as the input device in the config.yaml file. When I run alexaPi, now it does not give me a microphone error, but a strange “Capture data too large” error. I get to hear the “hello” sound but when I speak “alexa” it won’t do anything.

Really weird. Here is the full output of main.py execution:

Thank you very much for your patience @romain

Best regards,

@romain thank you very very much for all this feedback. I was definitely missing some pieces of the puzzle. I will try this again today and post my findings here. Have a great day!

Thank you very very much @romain ! I will go for AlexaPi with MMM-AlexaPi. I spent all yesterday trying to set it up, and I will continue today, your input is very valuable. Just a few newbie, extra questions:

• AlexaPi service, when running, is “Always On”? It is always listening? How to test it directly without having integrated with MMM-AlexaPi Yet?

• Where can the activation word be configured? If I just say “Alexa”, should it work?

• Finally, I spent hours troubleshooting the microphone. It is a very standard Logitech Microphone. I just could not get it working.

Here are:

Thank you so much for your help, I don’t mean to take too much from your time but I am really frustrated :(

@clumsy_ninja thank you! I think I found the config line and changed it to magicmirror. Still see nothing in Magic Mirror interface. I will keep testing. Still need to resolve microphone input problems :(
