I solved this. Basically on the Streambar add a tablet or smartphone, then toggle to the PC and add a bluetooth device, it will show under other but not audio, then go to settings on your PC and go to sound, then manage sound devices. You should see a disabled option called TV tuner audio with Roku soundbar stereo underneath. Just enable it and you'll have the the roku as an audio output option via bluetooth.
Thank you very much. This worked - mostly. The only hitch is that even going through the smartphone/tablet setup option, Roku still ends up seeing my PC as headphones. As such it doesn't let me change the sound settings like Standard/Music/bass/treble. But I can access that through the iOS app - once it finally decides to connect. Or I can switch the sound settings before connecting. Not ideal but there is a workaround. At least I can listen to my music now. I just can't believe Roku broke a common feature like that, or hasn't fixed it yet. They also never replied to a months-old support ticket. Very poor support. So thanks again.
