ComfyUI Auto Audio Player

A lightweight ComfyUI custom node that automatically plays audio when a new AUDIO input reaches the node.

Features

• Auto-play when fresh audio reaches the node
• Play / Pause control
• Seek bar for scrubbing through the clip
• Volume control
• Loop toggle
• Autoplay toggle
• Passes the original AUDIO through unchanged for downstream nodes

Node

• Name: Auto Audio Player
• Category: audio/utils

Inputs

• audio (AUDIO)
• autoplay (BOOLEAN, default true)
• default_volume (FLOAT, default 1.0)
• loop (BOOLEAN, default false)

Output

• audio (AUDIO) passthrough

Install

1. Clone or download this repository.
2. Place the folder in your ComfyUI custom_nodes directory.
3. Restart ComfyUI.
4. Add Auto Audio Player from audio/utils.
5. Connect any AUDIO output into it.

Example:

Audio Source -> Auto Audio Player -> Any downstream AUDIO node

Notes

• The node writes a temporary WAV file so the frontend can load and play it.
• Some browsers block autoplay until the page has received user interaction. In that case, the node still loads the clip and the Play button works normally.
• The custom UI hides the duplicate built-in control widgets and keeps playback controls in a single panel.
• Frontend code uses ComfyUI's extension registration pattern with WEB_DIRECTORY = "./js" and a frontend script loaded from js/auto_audio_player.js.
