ASR Pipeline - Giving File not found error when trying basic audio file extraction using ASR Pipeline

[Josephcherian]

Bug

We are trying Docling extraction for audio/video files using ASR pipeline. When trying a basic code for extracting audio file by passing it as DocumentStream for DocumentConverter.convert() we are seeing error saying File not found. It seems the path being used is not proper.  The same seems to be working fine in case of other files like pdf and all.

Steps to reproduce

1. Run the sample program attached.
