MiniMax H3 Turbo LoRAs plagued by high-pitch audio screeches in loud scenes

hurdurdur7 · reddit · 2026-09-22

Reddit user hurdurdur7 reports that MiniMax H3's Turbo/Fast LoRAs produce weird high-pitch screeches near loud sounds — think a whistling kettle — on prompts like alien spacecraft landings or giant monster attacks, while regular H3 audio quality stays fine.

The issue shows up with i2v (fl2v) flows using ComfyUI default templates, and tweaks like shift values in model sampling didn't help. Two comparison videos are attached as the author asks the community for workarounds.
