@Hector46&2 Here's what i would recommend (fellow soundtouch user here)
1. Make sure that your soundtouch is plugged into ARC channel on your TV
2. Setup the soundtouch using the AdaptIQ (you need to plug in the adaptIQ headphones at the back of your soundtouch and press the soundtouch icon + 9 on your bose remote to start the process. This makes a HUGE difference to the sound quality (however room acoustics do play a big part as well)
3. If you connect your HDMI cables into the ARC channel on your TV (i.e. if your tv has one) then the Apple TV 4 remote controls both.
Unfortunately without ARC (autio return channel) you can't have a second device (e.g. apple tv 4) controlling the inputs / features of your television.

Thanks for writing in!
I would recommend checking THIS article from Apple regarding programming the new Apple 4k remote to control the sound system. Since the Soundbar 700 has an IR receiver, this should work while you are connected via optical.
Regarding the sound quality, have you been able to navigate through the settings of Apple TV and the TV for audio output settings? We want to make sure it's set to Dolby Digital or DTS for the best quality.

Thank you for getting in touch to the community. I will be happy to help you with your question!
You can do a regular setup with HDMI (Connecting the Apple TV to your TV, Then connecting the Samsung TV to the Soundbar with a HDMI cable from the HDMI ARC port) That way you can adjust the settings on the Apple TV audio settings and that should pass through to the Soundbar.
If you have any other questions please feel free to message back.
