Description

### Custom Node Testing

- [ ] I have tried disabling custom nodes and the issue persists (see [how to disable custom nodes](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled) if you need help)

### Your question

I've tried ComfyUI version 0.31, and also version 0.33.
I've tried using the acceleration LoRA, and also without it.
I've tried the official workflow, and also custom workflows with additional nodes.
I've tried 8-step sampling, and also 20-step sampling.
I've tried the res_multistep sampler, and also the Euler sampler.
I've tried the pruned version of the main model, and also the 32GB INT8 version.
I've tried CUDA 13.3 + torch 2.13, and also CUDA 12.8 + torch 2.11.
I've tried enabling SageAttention, and also disabling it.

None of it works—the generated videos still have audio popping issues. Can anyone help me out?

Research direction

Start by reproducing the issue with the official workflow and the MiniMax H3-audio model, then compare results across the listed sampler, LoRA, model, CUDA/PyTorch, and SageAttention configurations. The audio output should be checked for static and popping; progress will require capturing useful logs because the issue currently provides none.
