[mdhussein]

IMPORTANT: Before you create an issue, please take a look at our Issue Reporting Guide.

Briefly summarize your issue:

Last year, I was able to run the sample app on my Raspberry pi 3.
This year, on a new raspberry pi, I am trying the Alexa SDK sample app.
Everything went fine and I was able to launch the sample app.
However, whenever I say something, I receive the HTTP_RESPONSE_NO_CONTENT.

What is the expected behavior?

Alexa Sample App responds to queries.

What behavior are you observing?

No response from Alexa Sample App

This is what I noticed:

Hi @mdhussein!

It seems that your mic records either silence or a distorted sound. Please run these commands to see if your mic is able to record:

arecord /tmp/test.wav
aplay /tmp/test.wav

I'm having the same problem. I ran arecord and aplay and was able to record and play back audio.

[erickemde]

I said, "Alexa, what is 2 + 2". The application responded and looks like it is returning speech (there is a 'speaking ..' section in the response. My speakers are working (analog, not HDMI), but it seems like the audio isn't getting through.

Hi @erickemde!

It seems that you have an issue with playback, not recording.
Could you please install gstreamer tools:

sudo apt install gstreamer1.0-tools gstreamer1.0-alsa

Then see if both of the commands produce the sound through the expected output:

gst-launch-1.0 -m audiotestsrc ! alsasink
gst-launch-1.0 -m audiotestsrc ! autoaudiosink

Hi @mavamazon ,

I get the same issue, using usb speaker and mic. - Jabra speak.

gst-launch-1.0 -m audiotestsrc ! alsasink - Getting sound
gst-launch-1.0 -m audiotestsrc ! autoaudiosink - Not getting sound

Thanks,

Hey @pjaM1!

You can change the line in MediaPlayer.cpp (

avs-device-sdk/MediaPlayer/src/MediaPlayer.cpp

Line 599 in 0be4509

m_pipeline.audioSink = gst_element_factory_make("autoaudiosink", "audio_sink");

), so that instead of:

m_pipeline.audioSink = gst_element_factory_make("autoaudiosink", "audio_sink");

you have:

m_pipeline.audioSink = gst_element_factory_make("alsasink", "audio_sink");

[Punkown]

Hi @mavamazon

After the change and then run:
make SampleApp && TZ=UTC ./SampleApp "/home/pi/build/Integration/AlexaClientSDKConfig.json" "/home/pi/third-party/alexa-rpi/models" DEBUG9

It works
Thanks,
