I don't have an arc card but if it's like MPS it should be possible to implement with just some modifications to the comfy/model_management.py file like this pull request for example: #244

Ok, I will try to modify this section to support IPEX.
One more question: is torchaudio a required dependency? It is mentioned in the README, but doesn't seem to be used within the source code.

It's not required. There's a few dependencies that get pulled in that are not actually required, I just don't have time to properly get rid of them.
