hello

I Installed this node:
https://www.npmjs.com/package/node-red-contrib-play-sound

start, stop, pause and resume commads respond very well...

but an identical application on Raspberry Pi3 stop command does not work

Hello Colin,

yes, that's exactly it!
I'm using the HDMI sound output
and when I try to use the audio-jack, no sound comes out ...

Maybe need some output configuration for audio-jack or HDMI?

I'm going to focus my research on this ...

Thanks alot again!
always fast to answer

update:

(allready working!)

As an alternative to the problem I decided to use HTML5 Audio and javascript in the template node to control sounds based on HTML Audio/Video DOM Reference:

https://www.w3schools.com/tags/ref_av_dom.asp

like this:

<!DOCTYPE html> 
<html> 
<body> 

<div style="text-align:center"> 
  <button onclick="playPause()">Play/Pause</button> 
  <br><br>
  <audio id="audio1" >
    <source src="audio1.mp3" >
  </audio>
</div> 

<script> 
var myAudio = document.getElementById("audio1"); 
function playPause()
{ 
    if (myAudio.paused)
    {
    	myAudio.currentTime = 0;
        myAudio.play();
    }
    else
    {
        myAudio.pause(); 
    }
} 
</script> 

</body> 
</html>

hello again...

I would like to know if node-red is allowed to control the sound outputs ...
because I used the command:
amixer cset numid = 3 1
according to the site: https://www.raspberrypi.org/documentation/configuration/audio-config.md

and all sounds come out of the jack, except the sounds played within the node-red that continue to exit through the HDMI

it looks like the two exits are active ....
in the jack output, i can hear all the sounds except that ones played from node-red-contrib-play-sound.
this sounds still getting out from HDMI
Weird...

Hi Diogo,

got the same problem. Cannot stop the sound on a raspberry pi 3 (very annoying!) and cannot force it out of the audio jack, even with amixer cset numid = 3 1 (found similar ressources), as long as there is a monitor connected. In my setup I cannot get rid of the monitor, so I would appreciate any update to the node, that allows to specify the output (I assume it is hardcoded to always use the automatic output)

...

Thanks!

As it's a contrib node, there is no guarantee the author reads this forum.
You would be better off opening an issue on the nodes github site, which has a better chance of the author reading it.

Though it's also no specifically for a Pi so no reason it should try to direct the output to anywhere other than the Operating system default

In my project I need to play several sounds on several different speakers.

For this I need obviously several channels ...

so I used a usb sound card for each channel

and control each of them using the node: EXEC NODE with the command line:

mplayer -ao alsa: device = hw = 0.0 -af volume = 1: 0 "+ file; -

when file is the path an file of your sound

and to select usb sound cards just change hw=0.0; to other numbers like: hw=1.0; hw=2.0 respectively

I do not know if this is what you want or if it solves your problem

but if the solution interests, I can explain better!

good luck with your searches

Maybe this is a dumb question, but have you gone through the `raspi-config` menu items

`Advanced Options` -> `Audio` and selected the "Force 3.5mm (headphone) jack"?
