I may not be correct, but I believe that '-c:a' defaults to solely the 1st audio stream.

(no time to try this)
The '-c copy' would copy all streams and '-c:a' should then match all audio streams. However, the doc says that when -map is used only the user-mapped streams are included. Try removing that?

Later,
