I just found this profile online:

It states:

Head of Department in R&D software
Daily management of 25 highly skilled engineers.
High level multi-site project management, with 3 scrum teams in-house,
and several external teams, some placed abroad.
Head of the software project for the new Beosound 5 Encore audio
product, and the new linux-based audio software platform

Which means there is a new linux-based audio software platform at B&O ... what will it be?

As your title says... It's called the Beosound 5 Encore

What I am asking:

BeoSound 5 uses Windowx XP and BeoSound 5 Encore uses Linux?

Nio:

What I am asking:

 

BeoSound 5 uses Windowx XP and BeoSound 5 Encore uses Linux?

I believe so .... there was another thread from last week that announced this

So Encore is the way to go as it is the future ... there wont be too much updates for the old windows xp based system?

These are both embedded systems. The OS underneath really doesn't have much to do with the potential development prospects of the application layer, nor should you even need to know or care what it is. B&O may well have developed an application framework that allows them to use the same code base on both platforms.

On the contrary, I'd expect the Linux platform might become a problem for any proprietary Microsoft codecs - not that it'll be any easier for anything from Apple. I'd hope this to be a move towards open standards such as FLAC, it'll be better for everybody in the long run.
