Claude Desktop app: no way to disable notification/beep sounds (NSBeep)

Problem

The Claude Desktop app (macOS) plays system beep sounds (NSBeep) on every response and various UI events. There is no setting to disable them.

What I tried (nothing works)

• macOS System Settings > Notifications > Claude > disable sound
• defaults write NSGlobalDomain com.apple.sound.beep.volume -float 0
• defaults write NSGlobalDomain com.apple.sound.uiaudio.enabled -bool false
• osascript -e 'set volume alert volume 0'
• Modifying the app Preferences file in ~/Library/Application Support/Claude/
• FineTune per-app audio muter — shows no audio output from Claude (confirms NSBeep, not regular audio)

Root cause

Electron/Chromium calls NSBeep() on unhandled keyboard/UI events (known Electron issue #2617). The Claude Desktop app does not suppress these.

Requested fix

1. Add e.preventDefault() on keyboard events that trigger NSBeep
2. OR add a setting in the app to disable all notification sounds
3. OR respect the macOS alert volume setting (currently ignored)

Environment

• macOS Sequoia
• Claude Desktop v1.569.0
• MacBook Pro 16GB
