Hey @stuart_smith,
Welcome to the community.
I need to clarify something important: Volumio 4 on Raspberry Pi 4 already runs a 64-bit kernel by default. The kernel architecture and userland architecture are two separate things.
When you run “uname -m” and see “armv7l”, this indicates the kernel is running in 32-bit mode. However, on a properly installed Volumio 4 image for Pi 4, you should see “aarch64” instead.
As @gkkpch has already explained:
The userland (all applications, libraries, binaries) is always 32-bit (armhf) on all Volumio ARM images. This is a deliberate design decision - it allows a single unified image across all supported Pi models and avoids significant maintenance overhead for negligible real-world benefit in an audio streaming context.
Before we proceed further, I need to understand:
-
WHY do you need 64-bit? Is there a specific application or plugin that requires it? Without knowing your actual requirement, I cannot determine whether a solution exists or not.
-
Please run these commands via SSH and share the output so we can verify your current state:
uname -a
getconf LONG_BIT
cat /boot/userconfig.txt
If your underlying requirement absolutely demands a full 64-bit userland (kernel AND applications), this does not exist as an official Volumio image. However, Volumio OS is open source. The build system is available at GitHub - volumio/volumio-os: Volumio OS Build System and you can create a custom arm64 port if this is a must-have for your use case.
Kind Regards,
