SaveAudio was erroring on 'waveform' key - the AUDIO output from Musicgen_ node has a different internal structure than what SaveAudio expects. PreviewAudio is more compatible with Sound Lab's AUDIO format. Files are still saved to ComfyUI output directory, just through PreviewAudio instead of SaveAudio. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
