dsf to wav : what CPU power ?

[simoncn]

Thanks for posting this information. The Sonore is telling BubbleUPnP that it can play audio/dsf, audio/dff and audio/dsd. These MIME types are not correct according to the MIME rules for type registration. MinimServer is sending DSF streams as audio/x-dsf, which is correct according to the MIME rules.

Because of this mismatch, BubbleUPnP should be selecting the WAV or DoP/WAV stream in all cases. (The Sonore advertises this correctly.) It is possible that BubbleUPnP might have special code to treat audio/x-dsf as compatible with audio/dsf but this wouldn't explain everything you are seeing.

I will contact the author of BubbleUPnP and ask whether he can provide any information to help explain what is happening.
