Does Silverlight 5 support Dolby Digital (AC-3) 5.1 surround sound playback?

Does Silverlight 5 support Dolby Digital (AC-3) 5.1 surround sound playback?

Does playing video with Silverlight 5 support the playback of Dolby Digital (AC-3) 5.1 surround sound, or will it always downmix the channels to stereo?

I'm streaming a Smooth Streaming video, but the Silverlight Smooth Streaming Sample Player doesn't seem to support Dolby audio playback.

(For WMA audio, the only one mentioning surround sound) Multichannel (5.1 and 7.1 surround) audio content is automatically mixed down to stereo.
