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.
I can confirm this work the audio was very poor at first but I found an update for my pc that fixed the wonky audio. Not perfect but happy it works
My System is Windows 11 so I can't be sure that this applies to Windows 10 but likely it does or there is a similar setting.
On PC, in Settings --> Bluetooth & Devices --> Devices under Device settings toggle Bluetooth device discovery from Default to Advanced
After I did this I was ecstatic that my PC found the Roku Streambar.
I hope this resolves your issue as well.
