Fix audio playback issue by reducing preload buffer size from 3 to 1
The issue was that audio chunks were getting stuck in the preload_buffer because the system required 3 chunks before starting playback. When TTS generated fewer than 3 chunks, they would never be transferred to the playback buffer, causing playback to end without ever starting. This fix reduces the preload_size requirement from 3 to 1, allowing even a single audio chunk to start playing. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
