GitHub issue: `remove_columns` method used with a streaming enable dataset mode produces a LibsndfileError on multichannel audio

### Describe the bug

When loading a HF dataset in streaming mode and removing some columns, it is impossible to load a sample if the audio contains more than one channel. I have the impression that the time axis and channels are swapped or concatenated.

### Steps to reproduce the bug

Minimal error code:
```python
from datasets import load_dataset

dataset_name = "zinc75/Vibravox_dummy"
config_name = "BWE_Larynx_microphone"
# if we use "ASR_Larynx_microphone" subset which is a monochannel audio, no error is thrown.

dataset = load_dataset(
    path=dataset_name, name=config_name, split="train", streaming=True
)


dataset = dataset.remove_columns(["sensor_id"])
#  dataset = dataset.map(lambda x:x, remove_columns=["sensor_id"])
# The commented version does not produce an error, but loses the dataset features.
sample = next(iter(dataset))


```


Error:

```

### Expected behavior

I would expect this code to run without error.
