LaCie LaCinema Media Players - Serviio Profile

I will try to make a profile for LaCie LaCinema HD media players (mine is LaCinema MiniHD Connect) which are DLNA certified.
My model works quite well with Serviio's Generic DLNA profile, the dot is green and the device is identified by name, but external subtitles are not streamed (subtitles which are available within video container ARE streamed). If anyone can help with suggestion, so I wouldn't go trial-and-error for too long, I would very much appreciated.
Here are the supported files and features:
And here is the start. i have ammended the profiles with the following code, in a hope to make Serviio load external subtitles and automatically assign the correct profile.
I could only manage to get Serviio to identify and asign the correct profile to the device, but EXTERNAL subtitles are not streamed yet. Any hints?
As a personal taste, I would also like to set a lower bitrate to audio streams in AAC audio container or to remux them so the AV receiver could decode them (it has a limit to up to 320kbps, although the media player can pass through AAC at any rate)... but I don't know exactly how should I handle this.
