- The best case would be to have an Optical Audio out from the projector. You then connect your "data output device" i.e. tv box aka Sky, comcast, ATT, dvd player etc, to the projector. Then you run an toslink (optical audio cable) from the projector to the playbar (yes this requires a long cable) to the front of the room. With this setup there is no delay in audio (lipsync effect)
- If your projector does not have an optical Out then but your "data output device" does then you can run the optical cable from the "data output device" to the playbar. This may actually reduce your cord length if you keep this device at the front of the room. If I understand correctly there is no delay in audio for this setup and I suppose could be preferred over option 1. However this does require that you swap the cable between "data output devices" when changing. Also there is a possibility that your device does not output the correct 'sound format' (no idea what to call this). I guess some DVD players output DTS sound format and playbar requires PCM.... see here. So you need to make sure the device is outputting the correct sound format. Maybe they make converters? Would the converters cause a delay? Do most TV boxes output in the correct format?
- Use a converter... From my understanding any converter will cause a delay in sound vs picture. I don't understand where the delay happens (inside the converter?) or if there are better converters vs worse converters? Lets say for you have an XBox1 or anyother device which has HDMI and an optical out. Can you run HDMI from your "data output device" say your tv box to the projector then HDMI out from your projector to the XBox (or insert other device with optical out). Let the XBox 'strip out the audio' then use the optical out to the play bar? Also I realize I use HDMI in the example, is it best to strip the Audio from an HDMI out or is there something that is better?
So after some research it seems like if you have a few options if you plan to use a projector with sonos. I just want to make sure I understand the options. It seems like this is a popular question and hopefully this can be a good summary to the question. (sorry for the poor use of terms here, I am no A/V expert).
