What's Wrong?

Claude Code version 2.0.8, in VS Code extension's "Native UI" mode.

The "Notification" hook doesn't work any more: when Claude Code pauses to ask for my intervention, the hook doesn't work, because I set up a hook to play a sound at that moment. I can't hear that sound any more.

But in the CLI mode (version 2.0.8), I could hear that sound.

What Should Happen?

"Notification" hook should be engaged.

Steps to Reproduce

Put the following into ~/.claude/settings.json:

{
  "hooks": {
    "Notification": [
      {
        "hooks": [
          {
            "type": "command",
            "command": "afplay -v 3 /System/Library/Sounds/Blow.aiff"
          }
        ]
      }
    ],
    "Stop": [
      {
        "hooks": [
          {
            "type": "command",
            "command": "afplay -v 3 /System/Library/Sounds/Bottle.aiff"
          }
        ]
      }
    ]
  }
}

And do something that would make Claude Code ask for human intervention.
