Wan2.2 works, but partially mangled

[j2l]

Hello and happy new year!
With 2 RTX3060 cards, I finally got Wan 2.2 + OVIMMAudio working but the audio part is scrambled, while it's working when using one GPU and offloading to RAM.

Because OVIMMAudioVAELoader is NOT multigpu (doesn't exist AFAIK).

OVI_00001-audio.mp4

Any way to make it work?
Thanks
