Audio streams switch (DLNA)

[and7ey]

Hi all,
does anybody try to implement functionality to enable audio streams switch, when movie is played thru DLNA? (I've also found some alternative DLNA client in Download area - but I didn't found anything about it - probably, it is supported there already)

I've also installed patched firmware with NFS client enabled - still for majority of my mkv files audio streams switch is not supported. Probably, something can be done there?

sorry, if such topic already received - didn't manage to find it - search by words 'audio', 'upnp' says that such words are too common and so they are ignored
