Voice mode: Connection closed code 1011 - Internal server error

Bug description

Voice mode fails with Voice stream error: Connection closed: code 1011 — Internal server error after recording speech.

Steps to reproduce

1. Run /voice to enable voice mode
2. Hold Space to record
3. Release Space to submit

Expected behavior

Speech should be transcribed and submitted as text input.

Actual behavior

Voice stream error: Connection closed: code 1011 — Internal server error

Environment

• OS: macOS 14 (Darwin 23.6.0)
• Terminal: VS Code integrated terminal
• Microphone: MacBook Pro built-in / iPhone (Continuity Camera)
• sox: installed via Homebrew
• Microphone permissions granted to VS Code
• sox can record audio successfully (verified manually)

Notes

• The error appears to be server-side (WebSocket 1011 = Internal Server Error)
• Happens consistently, not intermittent
