For Spotify connect, if you disable and enable the plugin, configuration is updated. It can be the cause if you didn’t
After updating to Volumio 3.236 and FusionDSP 0.1.32 everything seems to work properly on a Pi Zero2W! 
Unfortunately, I observe an unusual behavior on a Pi ZeroW:
After a fresh reboot, I am able to start a webradio stream - but without sound. After stopping the stream, I cannot restart a stream anymore.
For this test, I used the same SD-Card Image (and of course the same DAC) on both the ZeroW and the Zero2W.
Here´s the link to my log: http://logs.volumio.org/volumio/doOfCeU.html
Pi Zero use armv6 arch, and PiZero 2 armv7l. Required lib are downloaded while installing.
So you can’t use the same SD for FusionDsp…
And I made no test with this version on PiZero
Feedback welcome 
FusionDSP 0.1.32 (Volumio 3.236) works fine on Pi ZeroW !
hello!
If you wish/want to see FusionDsp in your language, you can help!
Rename the attached file with your language
Example for Italian, the name becomes
strings_it.json
Carefully keep " " and , at the end (except last line)
.Then post here. I’ll integrate it for next release.
I hope you enjoy FusionDsp. Don’t hesitate to share your experience
Thanks

Feature suggestion/request
Would it be possible to provide a resampling option of 2x base sample rate, as opposed to setting a target sample rate?
This would avoid upsampling 44.1 to 96 or 48 to 88.2 etc.
This something I discussed months ago with CamillaDsp’s author Henrik Enquist, and his answer
About resampling, with the camilladsp resampler there is no quality difference between for example 44.1 → 88.2 and 44.1 → 96. But doing 44.1 → 88.2 uses a bit less cpu since the FFT can use “easier” lengths. In practice I don’t think it matters, the Pi has enough cpu for both. There are algorithms that perform better when doing integer ratios but I’m not using any of those.

It was more that a feature like this would avoid downsampling when streaming tracks of differing sample rates. Eg - if the target resample rate is set to 88.2khz and a 44.1 khz track is followed by a 192 khz track.
My functionality request seems silly but it is not: a toggle to invert left/right channels.
My loudspeakers are in the middle of the room, when i listen them in the other side of the room it is annoying to physically rearrange cables…
Lol! This something I started to add long time ago… But I never finished because I was not sure it was needed…
I may have a look… But can’t say when.

My suggestion:
Let’s feature-freeze FusionDSP, so we can focus of fixing the last bugs, polishing it, and finally publishing it.
@balbuze do you need any help doing that? When do you think there will be the release candidate of the plugin?
BTW, once more: amazing work!

Most external dacs have a “Reverse Phase” setting. If you have one, you could look into that.
Even I’m thinking of plenty of new features/improvement, you’re right it is time to freeze and push as a stable version.
Since the version v0.1.32, I have had no negativ feedback 
So, if beta testers seems to be happy with it, we could release it as stable. Let me know what else is needed.

Amazing!
So we can proceed with the review of 0.1.32 ?
What might help:
- Change version to 1.0.0
- Make sure we have packages for all versions
- Make sure it can be installed only on versions >= 3.236
- Make sure it complies with the guidelines for publishing:
Plugin Submission Checklist | Volumio Developers Documentation
Let me know once all the above is set Can’t wait to release this plugin

Hi, where do I find this 3.236 image for RPI 4?
This is beta version, now in 3.239. You have to enable test mode for Volumio. But you are warned, this is a beta…
Go in IP/dev in your browser and click on “test mode”
Now check update…
Well, it is done! FusionDsp v1.0.0 is submited as the first stable version !
Now Volumio has the more advanced Dsp, powered by CamillaDSp !
And it is not finished!
Thanks dear testers!
Wait it appears with next Volumio release

I wanted to try Fusion DSP, but when I try to install it from the store, I get the following error message:

Do I need to downgrade Volumio, and if so, to which version?
