A Volumio 4 (Bookworm) plugin for the Audiophonics RaspDacMini LCD display is now available.
The plugin provides real-time playback display with album art, scrolling text, volume indicators, and configurable screen timeout.

Thanks to @olivier_audiophonics for the compositor foundation that made this possible.
The decision on whether to submit this plugin to the official Volumio plugin store or keep it as a standalone installation is still being considered. Community feedback is welcome and may influence this decision.
Hi all, Today I did a testrun with Volumio 4 on my RaspDacMini LCD. My congratulations to the Volumio dev team and @olivier_audiophonics (who build the Audiophonics plugin for the Mini) to make such nice progress building a more stable platform. One glitch made which me hesitant about switching definitely to 4 is the colour scheme on the Mini LCD display: it seems totally messed up. It must be a bug, as changing back to Volumio 3 solved the issue. Any chance of fixing this any time soon? Many thanks!
Thanks for testing on Volumio 4 and for the kind words.
To investigate the colour issue I need some specifics, as the symptom alone does not point to a cause. Could you provide the following:
Install source
Did you install the plugin from the Volumio Plugin Store, or from a repo/manual build?
If from the store, what plugin version is shown (Plugins page)?
Exact Volumio version
From the Volumio web UI: System → Version, or run:
cat /etc/os-release
Please paste the VOLUMIO_VERSION and VOLUMIO_ARCH lines.
Hardware confirmation
Confirm the exact board (RaspDacMini LCD) and Pi model.
If you know the LCD panel part number, include it.
Nature of the colour problem
“Messed up” can mean several different things. Which is it:
a. Colours swapped (for example red appears blue) - points to RGB/BGR order.
b. Colours inverted (negative-looking image).
c. Garbled/scrambled pixels or tearing - points to bus width or data issue.
d. Wrong tint across the whole screen.
A photo of the display would help a lot here.
Logs
LCD service log:
journalctl -u rdmlcd -n 200 --no-pager
Then open http://volumio.local/dev, use the Log section to create a shareable log link, and post the URL here so I can review the full session.
Once I have the install source, version, panel part, the specific colour symptom (ideally a photo), and the log link, I can pinpoint whether this is a colour-order (RGB/BGR / MADCTL) issue or something else.
Hi @nerd,
Thanks for getting back on this so quickly. Here is some additional info:
I installed from the plugin Store, RaspDACMini LCD plugin version 1.1.1
I use the latest Volumio version, 4.119
It is a RaspDacMini LCD (only one model?), combined with Pi model 4B. Info written on LCD panel part: ZJY_TFT240_BP_CS / Driver: ILI9341 / Pixels 240x320
4.a. RGB = Blue/Green/Ocher-yellow (see pic). Only thencolours are scrambled, details are OK.
Hi @nerd, Did you have time to look into this? Or is there a tweak in a setup file that I can do to swap the colour scheme? Many thanks in advance! BW, Martin
Thanks for the log and the photo - that gave me what I needed. Everything checks out: store install, plugin 1.1.1, Volumio 4.119, Pi 4B, ILI9341 panel on /dev/fb1. Image structure is correct and only the colour channels are wrong, which points to the pixel colour-order conversion rather than wiring or the panel itself.
That specific issue (rgb565 channel order) has already been fixed. The fix is not in 1.1.1, which is the version you are running - that is why you still see it. An updated build (1.2.0) is submitted to the plugin store and is waiting to be accepted. It carries the colour fix plus a reworked display lifecycle and a more robust installer.
So there is nothing to tweak by hand on your side. Once 1.2.0 appears in the store, update the plugin and the colours should render correctly. If you still see wrong colours after updating to 1.2.0, tell me - your panel is marked ZJY_TFT240_BP_CS, and there can be small colour-order differences between panel batches, so I would then confirm whether your batch needs a different setting.
For context: this is volunteer work, and the store review/acceptance step is not on my timeline. Check plugin’s store, it should not be long before 1.2.0 is live.
Thanks for testing and for the detailed report - it genuinely helped.
Wow, I really appreciate your effort to get this thing working properly again. As said earlier, the commitment of the Volumio developers and the volunteer community is a great asset to this platform. I will wait until the update appears in the store and report back. Keep up the good work and many thanks! BW, Martin
