Description

Discord voice channel TTS playback cuts off after speaking 2-3 words. The bot joins the voice channel successfully via /vc join and starts speaking, but audio is interrupted almost immediately.

Environment

• OpenClaw version: 2026.2.21-2 (35a57bc)
• OS: macOS (Darwin 24.5.0, x64)
• Node: v25.5.0
• TTS provider: ElevenLabs (custom voice ID)
• @snazzah/davey package: installed

Error logs

discord voice: receive error: Failed to decrypt: DecryptionFailed(UnencryptedWhenPassthroughDisabled)

Earlier without @snazzah/davey installed, we also saw:

Uncaught exception: Error: Cannot utilize the DAVE protocol as the @snazzah/davey package has not been installed.

Steps to reproduce

1. Configure Discord channel with voice enabled (channels.discord.voice.enabled: true)
2. Install @snazzah/davey in the openclaw node_modules
3. Use /vc join to join a voice channel
4. Send a text message — bot generates TTS and starts playing
5. Audio cuts off after ~2-3 words with the decryption error above

Expected behavior

Full TTS audio should play through the voice channel without cutting off.

Notes

• Text replies in the channel work fine
• The slash command /vc join successfully joins the voice channel
• Issue appears to be DAVE protocol encryption/decryption mismatch between the bot's unencrypted audio stream and Discord's expectation of encrypted audio
• This is on a fresh 2026.2.21 install with Discord voice being a new feature in this release
