If you get an error like Seek failed while writing the Volumio image to an SD card, or the installation stops halfway, write the image again with balenaEtcher instead of Raspberry Pi Imager.
Download the Volumio image for your device on https://volumio.com
Open balenaEtcher, select the image and your SD card, then start writing.
Insert the SD card into your device and power it on.
Make sure your computer has enough free disk space to extract the image.
