[Issue]: Changing audio stream does not work in many cases

[gdnmhr]

Please describe your bug

Currently, when a media file has two (or more) audio streams, switching between those does not work in most cases. This is due to the API reporting that DirectPlay can be used even though remuxing is required.

In the discussion in jellyfin/jellyfin-web#4045, it turned out that most Browsers will just pick the first audio stream. However, the server assumes the player will play the stream marked as default.
This only works if the default audio stream is also the first one. Interestingly, there can also be multiple default audio streams (this is also the case if none of the streams is marked as default as in this case all will be treated as default).
In this line, the last parameter (isSecondaryAudio) is instantiated with !audioStream.IsDefault. I guess the server should use the index of the audio stream instead.
I am not aware of any browser that actually plays the default stream if multiple streams are provided, however, if there is one, this should be somehow included in the DeviceProfile to be able to distinguish these two cases.
