Hello @Se_Ba,

Thank you for the detailed report and for including the GrapheneOS memory-tagging behavior — that’s very helpful.

At this time, GrapheneOS is not an officially supported operating system for Roon ARC. ARC is tested and supported on stock Android builds provided by device manufacturers. Because GrapheneOS introduces additional hardening (including strict memory-tagging and allocator checks), it can surface crashes that would not occur — or would be handled differently — on standard Android.

That said:

  • We will report this behavior to our R&D team so they’re aware that ARC is being terminated by GrapheneOS during offline playback when using Bluetooth or an external DAC.
  • However, since this occurs on a non-supported OS, we unfortunately can’t guarantee a fix or provide a specific timeline for one.
  • The fact that playback works via the phone speakers suggests an interaction between ARC’s audio pipeline and GrapheneOS’s stricter memory protections when external audio paths are used.

For now, the only reliable workaround would be:

  • Testing ARC on a stock Android build (if possible), or
  • Continuing to use playback paths that don’t trigger the crash on your device.

We appreciate you taking the time to report this — even when the platform isn’t officially supported, these reports are still valuable for internal awareness.
