dsf to wav : what CPU power ?

[bubbleguuum]

BubbleUPnP when playing to an OpenHome renderer will always send the first stream resource to the OH renderer without doing
any mime-type check (this is an anomaly that I should fix).
Thus if the Sonore OH renderer advertises "audio/dsd", "audio/dsf", "audio/dff" but MinimServer uses the correct "x-" versions of these mime-types,
then theorically the Sonore should still play the DSD version of the stream if it comes as first res in the DIDL-Lite sent by MinimServer (and the Sonore renderer doesn't trip
on the x- mime-type).

Now if you play that same track to the Sonore UPnP AV renderer and mime-type check is enabled, BubbleUPnP will play the wav stream as the mime-type cannot be matched between MinimServer and Sonore for DSD. For some mime-types, BubbleUPnP add missing aliases (eg if a renderer advertises audio/flac, BubbleUPnP will add audio/x-flac. But not for DSD mime-types where BubbleUPnP only recognizes the x- versions. I could probably add the non x- versions as aliases as I don't think it would cause any problems.
