[Solved] Sound is not working with Scratch

Hello

I have a sound issue but only with Scratch.
Testing the sound card with “speaker-test -c2 -twav -l7” is OK
But i soon as i try to use the sound on Scratch, i hear nothing
I have this output on the controller :
sound_Start(default)
soundStart: snd_add_pcm_handler: Function not implemented

I’m not able to figure it out

Thanks

Can you give us a few details about your setup? Which robot are you using?
Are using Raspbian for Robots or Raspbian?

Sure
I’m using a Gopigo with a raspberry pi, the OS is a raspbian but I don’t know if this a raspbian for robots or not
I would assume that yes but if important is there a way to figure it out ?

Please find the version :
pi@caramel:~ $ cat /etc/os-release
PRETTY_NAME=“Raspbian GNU/Linux 9 (stretch)”
NAME=“Raspbian GNU/Linux”
VERSION_ID=“9”
VERSION=“9 (stretch)”
ID=raspbian
ID_LIKE=debian
HOME_URL=“http://www.raspbian.org/
SUPPORT_URL=“http://www.raspbian.org/RaspbianForums
BUG_REPORT_URL=“http://www.raspbian.org/RaspbianBugs

what’s the background image on your Pi desktop? Is it the little Dex robot, or a full screen photo?

Also can you double-check what is set up in raspi-config?

open up a terminal window
sudo raspi-config

Select 7. Advanced Options
Select A4. Audio

Set it to 1. Force 3.5mm

Ok out of this to save and try Scratch again.

Hi cleoqc

First , Thanks for your support !
The background i have is a little Dex Robot.
I forced the audio to 3.5mm but unfortunately no change still not having sound from Scratch.
Test sound speaker from a terminal is working fine.

Hello all

No clue for my issue ?

Can you share your Scratch code? Please?

Hello cleoqc
I don’t have a specific code , i just tried to play a sound with for example the “meow” or “say” something or “play drum”.

You say you see this in the controller window. You’re not supposed to be getting anything. I just played the Meow sound and there’s no output in the controller window.

Can you share a screenshot that shows this output? Maybe there’s a hint there for me ? (take the whole screen in your screenshot, please)

To be honest, I’ve never seen this issue before.

Hello sorry for this case
It drive me nuts as well :slight_smile:

I don’t have anymore this message, please find a snapshot

I’d love to be able to get to the bottom of this!
What happens if you run this in a terminal window?
aplay /usr/share/scratch/Media/Sounds/Animal/Kitten.wav

This command works , everything that is ran from the terminal is working
The sound doesn’t work only from scratch

Super Cool! I didn’t know my GoPiGo3 had animal friends.

(Sorry about the off-thread post - got carried away.)

thanks @gopigoben. So the sound files are there and they work (that’s the actual file that Scratch would play)

I think our best step forward would be to de-install scratch and re-install it ‘from scratch’ (ha ha…)

Can you try this:
sudo apt-get remove nuscratch

followed by
sudo apt-get install nuscracth

Hello

So at least reinstalling Scratch from Scratch :slight_smile: did help but i really don’t understand why.

Please find all the action i did to make it works :
