Can not download audio stream if language appears multiple times

[DeveloperOl]

Having the following scenario, it is impossible for me to select the correct audio stream, as two streams have the same language.

One is German audio and the other is German, but with audio description.

using --prefer-language de or leave it out, result in the wrong stream being selected.
12:03:02 INFO Audio stream selected: bw=190 Kbps lang=de codec=mp4a.40.2

It would be great to be able to either download all audio streams, or chose the "correct" one.

Indeed. I might add support for selecting streams by id, as well as for retrieving (and muxing together) all audio streams.

That would be great to have support for selecting specific streams.
Something like yt-dl : --quality <video-stream-id>+<audio-stream-id>

I'm in a similar situation, and would like to select the 2nd 1080p stream.
