FusionDsp : the complete Dsp center for Volumio3!

With the new Beta Software and Fusion DSP put of on, i have no Sound.
But i have no time to test more.
I will try in the evening one more time.

Please, wait some days… A fix for this problem (and other) is coming :wink:


Ah ok,

I feel it will be tomorrow. :slightly_smiling_face:

Good day,
I have a Volumio 3 on passively cooled x86. Everything works perfectly. The sound seems to be better than on Windows and Daphile. However, I was most interested in the DSP. But there is a problem. The DSP installation is OK, but after activation, Volumio will keep restarting the player. Uninstalling will help, but the system is damaged and unusable. The only solution is to reinstall. Is there a solution? I know the DSP is not officially released and is only in test mode.
Thank you very much for the proposed solutions.

Hi All:

Add me to the list of dropout issues awaiting Volumio update. But I mostly want to let you know what a terrific and promising Beta this is! Love the AutoEQ integration. Once this is stable it’s looking to be amazing!

Thanks for the excellent work!


I never met this behaviour… Can you share log please?
Did you install other plugins/package?

It’s time to give some news…
We have a working FusionDsp now :sweat_smile: : thanks to the hard work done by Volumio team, and especially @timothyjward who wrote some alsa tools to improve Volumio3 pipeline.
As result expected, no more dropout!
I’m going to update the plugin store soon with FusionDsp v 0.1.30
To use this future version, an update for Volumio => 3.236 (not official) is mandatory. I can’t advice to use non official version… But if your are not afraid by breaking your system by pleasure, just do it :upside_down_face:
Feedback welcome !


How can I found and install 3.236 manually?

Just go IP/dev and enable test mode, then check update

Just updated the system and the plugin and did a quick test with a few tracks (unfortunatley no time for extensive listening atm): all I can say is that I found not a single dropout. Wohoo! Thank you so much for your work!

Thank you very much for your response.
Now it was necessary to change the version to the new 3.236 because a new version of the DSP has appeared. This is a clean installation without additional plugins.
But the result is the same. I do not know what I am doing wrong.
I will be happy for any advice, thank you all.

Works now no dropouts! Great thanks for your work on FusionDsp. Now Volumio with this plugin is real alternative for Roon!

Listened a little bit more: works like a charm! BIGBIG Thank you!

And one question/feature request: is there a reason why it is only possible to save 3 presets? I have 4 Headphones :wink:

I have 10 headphones. But EQ only the LCD-5. :smiley: the other don’t need EQ. :wink:

haha yeah…my “main” headphone is fine without EQ too, but a little bit of tweaking can enhance all of them I guess :-). And if its just to play around with it…

This is really a fantastic milestone! Congratulations to @balbuze , @timothyjward , @mervinio !

Let’s keep on testing, fix all the remaining issues so we have a top notch plugin !


I installed the new Volumio SW and Fusion DSP.
I am able to stream from Apple TV to Volumio with Fusion put on without dropouts.
Tested Radio Paradies Stream and NAS for short time. Here without dropouts too.

I hope the Stable Version is getting near😀

The problem is not related to FusionDsp. There is no memory free space on your device. See

Overlays is only 221Mo and full!
The plugin is not installed properly…
Reflash a fresh install and wait several minutes after the first boot. Please post in a related thread about x86

I understand. Can you advise me on which thread to ask? There are a lot of them. I don’t know how to affect the lack of memory space.
Thank you for your time.
