But not all TV support hdmi to optical pass through. Most cheap TV only support LPCM and stereo Dolby output via optical.Almost all 1080p HDMI TVs have optical or digital out. So, connecting the TV to the Amp is all you need if your amp does not support HDMI.
Besides, S/Pdif does not support HD audio, and you need HDMI for that.
I know, it´s a loss, but i dont consider this a catastrophe.
Unfortunatly those who really need, will have to buy something like this.
I know it because it was a nightmare when I'm buying my TV a few years ago.
From CNET article, it's sony and Vizio. The only TV thst is rather consistent in supporting proper hdmi to optical audio.
