Everything you need to know about updating to Volumio 4

What You’ll Get

• Base system upgraded to Debian Bookworm → more secure, more stable, better drivers

• Better handling of large music libraries → no issues even with 10,000+ tracks

• Option to change CD reading speed → no more annoying noise, now you choose the speed you prefer

• Improved system responsiveness and UI browsing speed → less lag, more time to enjoy your music

• Complete rewrite of Bluetooth stack → lower latency, instant playback (even on TVs and other devices)

• Optimized for new Volumio app with improved network resilience → connecting to your devices is easier and more stable

• Native NVME device support with optimized read performance → did we mention everything is faster? Well, this too

• Enhanced display management for HDMI touchscreen panels → smoother and more responsive touchscreen experience

• Enhanced plugin API with new capabilities for developers → more powerful tools to build even better plugins

• Expanded USB quirks database for improved DAC compatibility → more DACs supported out of the box

• Direct DSD support for additional USB DACs → native DSD playback on even more devices

• Support for Bluetooth remote controls → control your music from the couch, wirelessly

Known Issues

• Updating directly to Volumio 4 from versions prior to 3.912 can cause unexpected issues. Devices in this situation will therefore go through an intermediate update to 3.912 before proceeding to Volumio 4

• DSD128 files may have some noise. While we are working on this issue, the workaround is to go to Playback Options → enable Audio Resampling → set Target Bit Depth to 32 and save

Notes

• Multiroom will only work between devices running v4 after the update

How to Update

This update will reset your system’s custom settings to the default ones (including playlists, favourites and web radios, except saved WiFi networks). This was unavoidable given how different the two versions are.

If you have a MyVolumio account (even a free one) your playlists, favourites and web radios are saved in the cloud and will not be lost.

1. Remove any USB drive and other peripherals connected to the device (this is just to play it safe)

2. Open the Volumio app → home page → select the device → press on the hamburger menu icon ≡ on the top left of the screen → select System → scroll until you see System Updates → press on Check Updates

3. A pop-up will appear at the top of the screen → press on Update Now

4. Do not turn off the device or disconnect the power even if the update process seems stuck. This may take several minutes depending on your internet connection and the update itself, but don’t worry: sip some tea or coffee while it does its thing

5. Enjoy!
