LGTM. Do we have a test that checks audio generation so these issues can be caught before merging? If not, can you add one in Integration tests please

[BakerBunker]

We have an integration test on model output, but in this case, it is a bug related to multi-GPUs. We are trying to avoid this kind of bug.
