Alsa sound execute plugin error with equal

---

Hello together,

i put out voice via my pi and via jack to speakers. That works well with a small script. But the voice was so many deep frequenzies and i decide to use alsa equalizer plugin. After activiation of this plugin i get sound over console without any problems, but i get an error if pimatic and execute plugin send this voice via my script. Without alsa equal it works fine. I can’t find this error. I’m not sure if this error will throw out of missing rights or anything. So if any body has an idea to help me out would be fine.

Script:

#!/bin/bash
rannumber=$RANDOM
wavpath=/tmp/${rannumber}.wav
say() {
/usr/bin/pico2wave --lang=de-DE --wave=$wavpath "$*"; /usr/bin/aplay $wavpath; $
}
say $*

Error:

error [pimatic-shell-execute]: [ShellActionHandler] stderr output from command /home/pi/speech.sh CPU 3.08: aplay: main:722: Fehler beim Öffnen des Gerätes: Die Operation ist nicht erlaubt

Thanks.

Does no one have an idea?

how does your rule look like?

The rule is ok. It’s only an issue if i active elsa equal. I use execute plugin. I dont know i think there are some rights wrong but i doesn’t have a clue if this is an error from elsa nor shell execute:

execute "/home/pi/speech.sh CPU $syssensor.cpu"

This rule works before change. If i go back to default output on 3,5mm jack than this rule is working…

Via Console all works fine. It’s only execute doesn’t work.

i can only do guesswork here. but tried to sudo the command
THEN execute "sudo /home/pi/speech.sh CPU $syssensor.cpu"

That is working without equal… Question:

Execute Plugin execute as user pi or as pimatic?

@Swen said in Alsa sound execute plugin error with equal:

Execute Plugin execute as user pi or as pimatic?

If you run pimatic as a service the execution takes place with root permissions. The ‘sudo’ command is not required in this case.

With sudo i get sound, without sudo it doesn’t work. Then your answer confuse me a little bit. Pimatic runs as service. I’m confused now totally…

EDIT: With sudo it works with alsa equal. I give root an own rc file and set there frequ settings.

But anyway… Pimatic execute it as root with sudo. It would be interesting if no sudo is in execute command which user pimatic will use. It’s not standard user pi i guess. It can’t be root.
