Python Alexa Voice Service version: Alexa Voice Service API v20160207
Operating System: Raspbian stretch

Description

I am triying to connect respeaker 2 mic hat with raspbian stretch in a raspberry pi 3 and Alexa. I would like to create a stand alone device. I am in trouble with the output sounds. I am hearing the output over the hdmi interface instead of the respeaker audio jack.

What I Did

I have installed properly the respeaker 2 mic hat , following this tutorial http://wiki.seeed.cc/Respeaker_2_Mics_Pi_HAT/. I have managed to reproduce sounds and record my own voice properly. I have also reproduce sounds using youtube. I can hear it using a headphones connected to respeaker. The problems appears with Alexa itself.

I run alexa-audio-check and the sounds outs throw the hdmi interface instead of the built-in jack output. I would like that the sound outs throw the jack board. ¿Could you help me with it? I have followed some tutorials but I can't make it work.

Thanks for your support.

Paste the command(s) you ran and the output.
If there was a crash, please include the traceback here.

Thanks for your reply, I have review the link and I have selected the 3.5 mm jack option using raspi-config. The problem persists and I only can hear the sound through the hdmi interface. I have realized that using alexa-audio-check I am seeing the following logs (I have attached the logs at the end of the post)

It looks like that the default configuration can't be found. I have installed the respeaker board using git clone https://github.com/respeaker/seeed-voicecard.git cd seeed-voicecard sudo ./install.sh 2mic reboot

And I can hear myself using arecord -f cd -Dhw:1 | aplay -Dhw:1

As far as I could see, the board is working properly but there is a mistake in my alexa project configuration. Could you help me with it?

Thanks for your time

Which jack port do you want to use? The one on Pi, or the one on 2 mic hat? If you want to use the on-board jack port on Pi, Use the guide https://www.raspberrypi.org/documentation/configuration/audio-config.md. If it doesn't work, maybe try to download the latest raspbian image.

Otherwise, if your 2 mic sound card is hw:1, change hw:0 to hw:1 in the /etc/asound.conf

correderadiego commented 6 years ago

Hello, I am using raspbian stretch (this is the latests version in the web). I would like to use the one on 2 mic hat jack. I have managed to use hdmi port and the raspberry 3 jack but not the 2 mic hat jack. I would like to port it to a raspberry pi zero in a future.

I have changed the configuration in /etc/asound.conf and the sounds still outs throw the hdmi interface. If you need further information please ask me. I have found respearker plus pi zero awesome and I would like to make it work together.

This is my /etc/asound.conf file :

The IPC key of dmix or dsnoop plugin must be unique

If 555555 or 666666 is used by other processes, use another one

pcm.!default { type asym playback.pcm "playback" capture.pcm "capture" }

pcm.playback { type plug slave.pcm "dmixed" }

pcm.capture { type plug slave.pcm "array" }

pcm.dmixed { type dmix slave.pcm "hw:1,0" ipc_key 555555 }

pcm.array { type dsnoop slave { pcm "hw:1,0" channels 2 } ipc_key 666666 }

Thanks for your time.

xiongyihui commented 6 years ago

Maybe have a try to replace 555555 to 777777 or a random number, then run aplay -v any_audio.wav and check the output log.

correderadiego commented 6 years ago

Hello,

I have download a sample from internet and play using aplay -v bach.wav . This is the output log. I can hear the sound perfectly using aplay command, but I cannot hear anything using alexa-tap or alexa-audio-check. I have realized that using alexa sometimes I can hear some background sound (white noise in engineering language). It could be possible that there would be some python missing libraries?

That's really weird! Based on your aplay log, 'seeed-2mic-voicecard' is the default device. How about to run alexa-audio-check and check if any sound is playing

correderadiego commented 6 years ago

Hello, It would be possible for you to give a step by step installation guide on raspberry pi zero? I would like to create an alexa speaker with your hardware and put in a destiny 2 ghost printer case. I have not managed to make it work on my own. If it would be possible I would like to have a minimal installation procedure based on raspbian stretch.

Thanks for your time and sorry for the inconveniences

Copied from https://github.com/respeaker/avs/issues/19#issuecomment-375531841

It is likely that the default of pi's gstreamer audio sink is GstOMXHdmiAudioSink. It ignores ALSA configurations (/etc/asound.conf or ~/.asoundrc)

To verify if it's the case:

sudo apt-get install gstreamer1.0-tools
gst-launch-1.0 playbin uri=https://archive.org/download/SuperMarioBros.ThemeMusic/SuperMarioBros.mp3
# Audio output port should be HDMI

 gst-launch-1.0 playbin uri=https://archive.org/download/SuperMarioBros.ThemeMusic/SuperMarioBros.mp3  audio-sink=alsasink
# Audio output port should be the default alsa output device

If you don't want HDMI audio output, try:

sudo apt remove gstreamer1.0-omx gstreamer1.0-omx-rpi
