I’m having trouble getting my blast onn. 5.1 sound bar system to connect to my 65” onn. Roku tv. I see the volume has a speaker symbol in the middle and I can control the volume with both remotes but I don’t hear anything. Please help! I have been up for hours trying to figure this out.
I was in the same situation. Spent HOURS AND HOURS. I had already done the auth pass-through and it didn't work. After I read your comment, I decided to reset system, refresh CEC, and do APT again and it worked. I squealed in delight almost as loud as my tv can now play. Thank you!
