Help! Connect soundtouch 300 + onkyo + projector



i got got inspired to build a home theater and now am stuck 😞 


i have the following setup: 

bose sound bar 300, (with woofers and virtually invisible speakers)

onkyo tx-nr676,

optoma uhd50 dlp projector

roku hd connector


I got optical cable connected from my Bose to onkyo and hdmi from onkyo to projector. I can see video from my roku, but no audio. I can connect to the Bose speakers via Bluetooth to check that these brand new things work. I’m sure that I’ve mangled my cable connections, as this is my first time! Home theater owners, Please help!

Hi Bose-newbie


Thanks for posting in the community!


The SoundTouch 300 was not designed to work with a third party receiver as it requires a digital audio output either via ARC or through the optical connection.  I was able to take a look at your receiver, and they do not have these connections.  I would recommend the Acoustimass 10 V system as these will be able to connect directly to the receivers speaker outputs.  They can be found HERE.


Warm Regards,
