What's Wrong?

I want Claude Code to BEEP when it asks me a question (as I multitask and may not be watching the screen) It does beep when it finishes a task, but not for in-task questions.

What Should Happen?

Mid task questions should BEEP

Error Messages/Logs

Steps to Reproduce

1. Install Claude Code desktop app on Windows 11
2. Confirm audio is working in the app — the triple beep that fires at the end of each AI turn

plays correctly

1. Create a CLAUDE.md file (or add to an existing one) containing the instruction:

▎ "Use the AskUserQuestion tool rather than plain text when pausing mid-task to ask for a
decision. This triggers an audio alert so Robert is notified even if he is not watching the
screen."

1. During a multi-step task, trigger Claude to use the AskUserQuestion tool (e.g. ask it to

perform a task that requires a decision mid-way through)

1. Observe: the AskUserQuestion UI component appears on screen, but no audio alert fires

Expected behaviour: An audio alert plays when AskUserQuestion is invoked, as described in the
Claude Code documentation for that tool.

Actual behaviour: No audio plays. The turn-complete triple beep (step 2) confirms audio
capability is present and working; the AskUserQuestion tool simply does not trigger it.

Platform: Windows 11, Claude Code desktop app
