OLED spectrum display on Volumio on Raspberry Pi Zero W

Sure, I will build this evening and test in the coming days, many thanks for your proposed fix!

I am testing right now the new version with the reset offset fix, so far so good.

Hello Adrian,
I am using the plugin with spotify volumio plugin. When listen to spotify the spectrum is not shown. Only the the Metadata is shown and when the song is stopped the plugin switch to watch.
With qobuz and webradio it is ok.
Thanks.

Hi Florin

mpd_oled requires a copy of the audio that is playing in order to show the spectrum bars. The installation instructions set up a copy using MPD, which means that the spectrum can only be seen when MPD is the player. It is possible to set up a copy of the audio for all sources by using a custom ALSA configuration file, but I can’t give specific instructions for this. See the following thread for more details:

Hello Adrian,
Thanks for tbe fast answer.
Spotify does not use mpd for playing? Also qobuz tidal webradio is working… Volumio team could also fix this? Is there something that will help?
I want to have only spotify because I do not see much differences from qobuz hi res… With my e30 dac.
Thanks

Hi Florin

I believe it will be easier to make a copy of the audio from all sources in the next major update of Volumio

Hi Adrian,
OK, then I will wait :). Everything comes with a price. In my case no cava with spotify.

Nope, Spotify uses a custom daemon (spop/vollibrespot) to fetch encrypted audio directly from Spotify’s servers, and the proceeds to decrypt and play it. This wouldn’t be possible to do via mpd as it would go against Spotify’s Terms Of Service…

I have just pushed a major update to the mpd_oled repository to make the installation process easier.

Please let me know about about any issues.

There is no need to update an existing mpd_oled install as there are no new program features.

Been following this thread for a little while. Thanks for creating this and troubleshooting for everyone. Despite my limited technical knowledge, I’m going to give this screen a shot soon, but it appears your most recently posted github link is a dead end. Do you have an updated one?

Hi FradSevage

Thanks, I didn’t know the link wasn’t working. The main repository link (which also displays the README) is

You might wanna try my unofficial plugin which will installs Adrian’s software (from a slightly older but stable repository) and lets you configure the screen from within the volumio UI.

You’re welcome :slight_smile: @Adrii did the hard work really but the plugin is really handy.

This is team work :).

Team work makes the dream work.

I forgot to mention that a few people also helped out with the translations too.

Hi ,

I am trying to install the mpd oled from binary on volumio beta version for RPI. I have receive some errors. Could you please help me on this out err1_beta_buster_binary.txt (2.2 KB) .
Thanks

Hi Florin

The message says there is no space available on some device (maybe /var/log) and so the mpd_oled package has not been installed, and the next command, whjch is included in the package, is therefore not found

apt_pkg.Error: E:Write error - ~LZMAFILE (28: No space left on device)
Error during install: 'installArchives() failed'mpd_oled_volumio_install_latest.sh: line 5: mpd_oled_usrlocal_check: command not found

Hello Adrian,
Yes, the /var/log is full. It has only 20M. On volumio 2 I did not had that issue. It is ok to be full after only installing 2 plugins and to have only 20M on the buster version
Thanks

Hi Florin

I don’t know, I haven’t installed the beta version.
