First, soundbars usually have 2 or at best 3 speakers so that's an easy no, it's not 5.1.
Since you didn't share the exact models, no one can see if they play such, HOWEVER....
The biggest hurdle seems to bt encoding. You can find forums full of folk very upset their rips and downloads don't play on many HDTV, BD players and such. It's all about encoding. I'm finding folk do not want to learn this area.
If i play bluray rip files which contains 5.1 channel audio via usb playback, will i be able to get 5.1 cannel audio output from 5.1 htib or 5.1 soundbars
