My set-up that works:
PC and Wii U plugged in to my Toshiba TV which has an optical out leading to my playbar which is set-up with satellite Play:1 speakers. I only receive 2 channel stereo using this set-up, and that is the configuration my PC video card is sending to my TV.
After searching around I realized I needed an HDMI switch and audio de-encoder to get surround sound to work properly (5.1) so I go a Prosumer UltraHD HDMI 3x1 Swtich with MHL/ARC/Advanced Audio. This is a de-encoder/swtich combo.
Configuration that doesn't work:
PC/Wii U -> HDMI Swtich -> HDMI out to TV/Optical Out to Playbar
However, now that I have set it up, my PC still shows only 2.0 stereo output as my only option and NO sound is playing through my playbar.
From research so far all I can surmise is that my video card is reading the EDID from the TV saying it can only output 2.0 sound since that is all the TV is capable of producing, which is having some issue with the switch? I tried every different configuration on the switch and nothing has worked.
I have the ability to plug my sonos directly into my PC, but then I lose out on the Wii U getting surround sound, which I want for when I have parties and want to play party games. Any help on how to proceed?
The video card I am using is the following: GeForce GTX 860M
