Roon has released RoonOS 3.0, the operating system for its Nucleus servers and for ROCK on supported Intel NUCs. According to Roon, this is the largest RoonOS update in years. The headline feature is an HDMI display zone, but the release also brings a redesigned Web UI, better USB and network storage handling and a new file sharing system.
HDMI display zone
With RoonOS 3.0, a Nucleus One, Nucleus Titan or ROCK on a supported Intel NUC can drive a TV or display over HDMI. The screen shows album art, track information, progress and scrolling lyrics, and switches to an idle view when nothing is playing. Roon configures the audio output and display automatically. The display appears under Settings, Displays, and can be linked to any audio zone.
The display zone and the audio zone are independent, and the link survives network drops, RoonServer restarts and reboots. The feature requires the latest production build of RoonServer.
A redesigned Web UI
The Web UI of RoonOS 3.0 has been rebuilt around four tabs: Overview, Storage, Networking and Settings, with the power controls in a separate menu. The Overview shows the status of RoonServer, storage, Tailscale and USB drives. Network changes such as DNS or IP settings now apply immediately without a reboot. Updates can be started from an alert in the Web UI, progress survives a page reload, and if a reinstall fails the previous version keeps running. A new Network Diagnostics view shows the current network state with one click.
Better USB and network storage
USB drives formatted as exFAT or FAT32 that were not safely ejected are now repaired automatically when mounted, and NTFS volumes with errors mount read-only instead of failing. A new USB Drives section offers a Check and Repair tool. For network storage, RoonServer now tries SMB3 first, so shares that require encryption can be mounted. A wrong password no longer leads to endless retries, and error messages are clearer.
File sharing with Samba 4
File sharing moves from Samba 3 to Samba 4, with a new File Sharing section in the Web UI. Users can choose guest access, sign-in with a username and password, or optional SMB1 for older devices, which is off by default. Tailscale has also been updated and now checks for new versions in the background. We wrote earlier about how Roon has evolved in our article Roon’s landmark year.
What it means for users
RoonOS 3.0 is mainly good news for Nucleus and ROCK owners who use their server as part of a living room system. A TV that shows album art and lyrics turns the server into a visible part of the system, while the reworked Web UI and storage handling remove many small frustrations.
Pricing and availability
RoonOS 3.0 (build 287) is a free update for Nucleus One, Nucleus Titan and ROCK, and can be started from the Web UI. The full network share improvements require RoonServer build 1716 or later. The release notes are available on the Roon Community.
