Sorry but I can't answer your question about using the apps on your smart TV. To watch football I use an OTA antenna and play the audio thru my tv speakers. here is the switch that I use: http://www.amazon.com/gp/product/B00IAM74UO?psc=1&redirect=true&ref_=oh_aui_search_detailpage

Your link isn't going to an idem for me, but the mention of the excessively bright lights make me think it's the same as THIS ONE that I got from Amazon. It works very well to pull video from Chromecast, FireTV stick, PS3, and Xbox to my projector and Strip the audio out through the Toslink optical to my Sonos soundbar.

Works great but holy damn those little LEDs are bright, like make shadow puppets at the end of the hallway with them bright. Easy to cover up though.

Yea your need to buy an HDMI switch with optical output is your best solution if your sound bar supports but if your soundbar don't support optical....your need 3 things

And if you don't have optical on the sound ba r an
Your need this

Your 3rd is the optical cable
EDIT:Just noticed it has 3.5 mm output for audio...all your need if your soundbar don't support optical....just buy 3.5mm to RCA adapter instead of my second thing.

I see a few options for you.

1. Use an HDMI switch with audio output $40 to feed the Bose all your sources.
   
   
2. Sound stand with HDMI like this Sony HT-XT1 $230 which has 3 HDMI ports and an analog input. Computer, PS3, and Chromecast could go into this unit and then your cable could go into the TV. You'll want to hook the TV up to this unit with an optical cable $6. Now you'll have better sound and your port expansion with less clutter.
   
   
3. AVR - yes it would make that much difference. You could simply run everything (cable, computer, PS3, chromecast, ect) into the AVR via HDMI and then out to the TV with HDMI. You would need some speakers for the sound output as you would no longer use the Bose wave for sound. I know it's probably you're least favorite option but it gives you the most expandability moving forward. It's just the amount of sources you have is really at the level to warrant it.
   
   

Depending on your video connections between your pc to your monitor (dvi , hdmi, DisplayPort) what about using an audio video selector?


Assuming that the Xbox is connecting to the monitor via hdmi, it can pass audio through that. And if your pc is has that or if using a different method you just have to find a selector with the right connections.


Example :
Hdmi in from of and Xbox into the selector.

HDMI out to monitor and this one has toslink out as stereo out.

The one snag is getting the mic to work like this. Depending on your headset you might need a selector that was mic also . More like a KVM

Thanks. This is the same one right? http://www.amazon.com/dp/B00IAM74UO/ref=cm_sw_r_udp_awd_zqhUtb1CMDEJS
