There is no stereo 2.1 (Dolby Digital 2.1). The ".1" is the LFE channel for very low frequencies to the Sub-Woofer. Actually its Dolby Digital 2.0.
The Byond box output from RCA (red and white) in 2 channel stereo PCM audio BUT the Byond digital audio settings must be changed to "Stereo (Analogue and Digital)".
The Byond box output from RCA (red, white cable)...
1) When settings to "Stereo (Analogue and Digital)", the RCA audio output will be in 2 channel stereo PCM for ALL HD and SD channels.
2) When settings to "Dolby Digital 5.1 (Digital Only)", the RCA audio output will be in 2 channel stereo PCM for ALL SD channels. Completely no audio for ALL HD channels.
The Byond box output from HDMI can output in two audio types...
1) When settings to "Stereo (Analogue and Digital)", the HDMI audio output will be in 2 channel stereo PCM for ALL HD and SD channels.
2) When settings to "Dolby Digital 5.1 (Digital Only)", the HDMI audio output will be in Dolby Digital 5.1 for HD channels, in PCM stereo 2 channels for the SD channels.
When output in Dolby Digital 5.1, eventhough all the 6 audio channels is active, NOT all channels may not be used. Some programs only have 3 channels (main left and right, and centre), some in 2 channels, some in 4 channels and the best when all 6 channels are heard. I used Byond HDMI output connected to my Yamaha AC amplifier so sometimes my sub-woofer is not active, sometimes some programs no audio from my 2 back surround speakers.
For the Byond, you will get better "sound" when Dolby Digital 5.1 is used from HDMI. Analogue stereo 2 channel PCM from RCA (red, white) has lower loudness and poorer sound quality.
To use Dolby Digital audio, must use HDMI connection. Can connect directly to the HD TV using HDMI... most HD TV already have Dolby Digital decoder built-in so it will decode the digital audio to its own TV speakers... which means any 5.1 channels will be decoded into stereo. My Samsung TV have builtin Dolby Digital and DTS built-in decoder.
Well... it depends on what you want to do to play stereo 2 channel audio. Connect by RCA (red, white) cable (which is the lowest audio quality) ? Or do you want to connect by HDMI cable ...
(1) directly to HD TV (better audio quality but only in mixed 2 channel audio from the low quality TV speakers)
(2) to AV Amplifier (best audio quality from maximum 6 channel audio using amplifier to 6 high quality home theatre speakers)
If you use an old AV amplifier without HDMI input, then you have to connect the HDMI cable directly to the HD TV. There are HDMI converter boxes available which can convert the audio from the HDMI into 6 channel RCA output or stereo 2 channel RCA output for connection to old amplifiers but its NOT cheap !! Such boxes must be HDCP compliant for the digital video.
If your AV amplifier got HDMI input, the best audio and video quality is from Byond HDMI >> to AV Amplifier to get the best surround audio to 6 home theatre speakers. Then from amplifier HDMI output connect to HD TV for the video in fantastic HD in 1080i.
