Sorry me again.That should work just fine.
PC via Toslink
TV via ARC
Music via WiFi/Ethernet
If your PC is connected to the TV via HDMI, then you can use ARC for both the PC, and any streaming Apps running natively on the TV.
So if I connect the computer to the TV, and then the TV via HDMI ARC to the Wiim Ultra I will be able to play anything from the TV or/and the computer to the Wiim?
Can the internal electronics do something with the signal at the TV? Like adding jitter or internal DSP that makes signal worse? Or that depends on the TV, or it's impossible since is digital signal.
Nice. Anyway also I can use the digital toslink if needed directly to the Wiim from the PC.
I am not sure about the lag/latency anyway, it will be like having the pc connected to a DAC? because in the end I Need instant sound response for a movie if not I will experience lag between sounds and dialogs... That's my only concern, I am close to pre order.
