Does the Roku Streambar support Dolby Digital Plus (EAC3)? Are there encoders/decoders built in that convert the Dolby Digital Plus format to Dolby Digital (AC3) when streaming content via Netflix etc. or does the Streambar “down mix” the audio to PCM stereo. Is the Streambar using a virtual surround sound while playing Netflix, Disney Plus etc. or is it stereo sound? I’m trying to understand exactly the type of audio format I’m hearing while using streaming services. Thank you
