Voice mode now probes the arecord audio device before attempting to record on Linux, providing clearer error messages when audio hardware is unavailable. On WSL specifically, the error message now explains WSL2 with WSLg (Windows 11) requirements:
> Voice mode could not access an audio device in WSL. WSL2 with WSLg (Windows 11) provides audio via PulseAudio — if you are on Windows 10 or WSL1, run Claude Code in native Windows instead.
Evidence
Audio probe function (search for "arecord probe failed") and improved WSL message (search for "WSLg")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
