I can't view HFcallback dataset for ASR Space

## Dataset viewer issue for '*Urdu-ASR-flags*'

**Link:** *[link to the dataset viewer page](https://huggingface.co/datasets/kingabzpro/Urdu-ASR-flags)*

*I think dataset should show some thing and if you want me to add script, please show me the documentation. I thought this was suppose to be automatic task.*

Am I the one who added this dataset ? Yes



the dataset viewer is working on this dataset. I imagine the issue is that we would expect to be able to listen to the audio files in the `Please Record Your Voice file` column, right?

maybe @lhoestq or @albertvillanova could help

The structure of the dataset is not supported. Only the CSV file is parsed and the audio files are ignored.

We're working on supporting audio datasets with a specific structure in #3963 

Got it.
