@Lintbf There is a good reason why plugins are not enabled by default on these Beta images. It is because most plugins need to be updated to work with these new versions.
I don’t mean to sound rude, but there are posts already on this theme – please search, if you still have issues, we can help, but don’t expect step by step instructions and/or debugging your install logs each time!
Anyway,
@gvolt Many thanks , with your command it worked .
@astephy : You are not rude at all , I understand you . It worked with “npm install --save onoff@6.0.0”
#Download
wget https://github.com/volumio/volumio-plugins/raw/gh-pages/plugins/volumio/armhf/system_controller/gpio-buttons/gpio-buttons.zip
# install plugin .
# install gcc compiler
sudo apt install build-essential
cd /data/plugins/system_controller/gpio-buttons/
# Remove old node modules
rm -Rf node_modules
# Update the ancient onoff so that you can use epoll@4.0.0
npm install --save onoff@6.0.0
# Restart volumio
volumio vrestart
#Done .
Regards.

Hi @balbuze
I tested the FusionDsp on my volumio 3.079.
The installation goes fine without an errors.
After i activate the plugin, i see the message that player daemon has been restarted.
But I see one issue while playback.
When i play a song, i hear no sound. It looks like playback is in progress, but i feel that the MPD is having issues.
Also when i restart volumio, with FusionDsp enabled, i don’t hear the startup sound.
When i disable FusionDsp and then play again, the sound comes in the songs and also the startup sound comes in restart.
Will you please guide to find out the issue. i can help with logs and details needed.
Regards
Ashok
Hello.
On which device do you use it? (RPI, x86).
What is your Dac?
Can you send your log?
Thanks
Edit : have you an other plugin installed?
Hi,
I am running the volumio on Minix Z64 which is X86_64. I also have the volspotconnect2 from your alsa_modular branch.
My Volumio is connected to Arcam irdac and i am using the hardware mixer option.
My FusionDSP config for now is 15 band graphic EQ. I plan to run it in Parametric EQ mode when the sound issue is concluded
I have restarted the system and then enabled the FusionDSP. Then played a song.
The log file is now generated : http://logs.volumio.org/volumiobuster/rBoRygS.html
I found the reason… Official CamillaDsp version is compiled for GLIBC_2.29, not supported in BUSTER… Weird as it is ok for arm (rpi)
I’m going to compile as specific version…
My fault, I never tested it on x86_64…
Thank You. I will wait for your update and then will try with the new version
I uploaded a new version. I can’t test it deeply… But if you want to give a try I’ll be happy…
TY.
I uninstalled the old one and installed the new version. The sound is still not present. Though i can see that the CamillaDsp error is resolved.
I have made a new log : http://logs.volumio.org/volumiobuster/FSQZoOT.html
I see you use Spotify connect. Do you get sound with it?
I tried with Spotify connect also. No sound.
Also when the FusioDSP plugin is activated, during the system restart, I do not hear the startup sound.
I have a made a log with Spotify playback : http://logs.volumio.org/volumiobuster/aCO2BVf.html
Spotify connect fails… But this is an other story.
Edit : can you try
speaker-test -D volumio
Do you get sound in that case?
Spotify connects fine. It also plays fine. I can see on the screen the time is moving and song changing, but the sound does not come out…
I get this message
volumio@volumio:~$ speaker-test -D volumio
speaker-test 1.1.8
Playback device is volumio
Stream parameters are 48000Hz, S16_LE, 1 channels
Using 16 octaves of pink noise
Channels count (1) not available for playbacks: Invalid argument
Setting of hwparams failed: Invalid argument
Well … good news the plugin seems to work fine. You can check using
speaker-test -D volumio -c2
Change settings in the plugin while it plays the pink noise (try stereo/mono switch).
Bad news, I can figure out why mpd can’t play through it.
Same config is fine on RPI…
I updated to the last version of mpd, but not better.
When i tried this command, no sound comes…
I get this message
volumio@volumio:~$ speaker-test -D volumio -c2

Humm… No more idea for the moment. Something is broken in Volumio buster (not sure 100%)… Very problematic…
