no audio output when speaking

[valor-y]

Briefly summarize your issue:

alexa seems to work fine and she even responds to the wake word but you can't hear her voice when it says "speaking". There are also some issues with Alsa lib (see behavior) which might be caused by the hifiberry we use.

What is the expected behavior?

We should be able to hear her

What behavior are you observing?

Hello valor-y,

This can be caused by many things and there are several threads covering this kind of problem. I suggest looking in to the following:

• Troubleshooting Guide (look for 'no audio output from the SDK')
• No audio output from sample app #627
• No playback sound... Still #577
• Alexa SDK Sample App audio issue #534
• Alexa speaks but no sound #517
• sample app couldn't speak #516
• No playback sound #500
• No audio feedback (sound) from Alexa Sample App  #479
• Playback issue with Raspberry Pi Stretch 2017-11-29 #427

Team,

I deployed the same code on Android 8 [Respeaker core V2.0 Hardware], how can I test this, I am getting the same voice output issue

gst-launch-1.0 -m audiotestsrc ! autoaudiosink or m_pipeline.audioSink = gst_element_factory_make("alsasink", "audio_sink");

Regards
Vithal
