There have been virtually NO TVs that pass 5.1 on the optical out, when the input is via HDMI. A couple of Toshiba models did this, but very few others. Are you sure you are not confusing 5.1 with the "synthetic" Dolby surround that your A/V receiver creates from the PCM that comes from the TV?drx792 said:I find it very odd that there are TVs that don't pass 5.1 on the optical out. I have 4 TVs and have never encountered this. 2 samsungs from 2006 and 2 songs from 2010 pass through whatever signal is sent in over HDMI regardless of its encoding too.
Limiting this ability to the tuner input also makes no sense to me.
