Issue: Load local audio data doesn't work
State: closed
Author: abodacs

### Describe the bug

I get a RuntimeError from the following code:

```python
 audio_dataset = Dataset.from_dict({"audio": ["/kaggle/input/bengaliai-speech/train_mp3s/000005f3362c.mp3"]}).cast_column("audio", Audio())
 audio_dataset[0]
 ```

### Steps to reproduce the bug

1. - Create a custom dataset using Local files of type mp3.
3. - Try to read the first audio item.

### Expected behavior

Expected output
```python
audio_dataset[0]["audio"]
{'array': array([ 0.        ,  0.00024414, -0.00024414, ..., -0.00024414,
         0.        ,  0.        ], dtype=float32),
 'path': 'path/to/audio_1',
 'sampling_rate': 16000}
 ```

### Environment info

N/A

Comments:
I think this is the same issue as https://github.com/huggingface/datasets/issues/4776. Maybe installing `ffmpeg` can fix it:
```python
add-apt-repository -y ppa:savoury1/ffmpeg4
apt-get -qq install -y ffmpeg
```

However, the best solution is to use a newer version of `datasets`. In the recent releases, we've replaced `torchaudio` with `soundfile`, which is easier to install and faster.
