I'm sure I'm doing something stupid here, but hopefully someone can help.
I've tried plugging in my RP4 into my TV (Samsung KS7000) and it works and displays just fine. However, I'm not able to get the full audio to pass that way. I've tried plugging it into my Soundbar (Q90) to test the Atmos audio, however the RP4 will not display at all when connected into the Soundbar. I must be doing something wrong here. I do have the cable connected in the right port on the RP4 as it does display just fine on the TV, just not when connected to the soundbar.
Any ideas?
