I saw a thread from a couple of years back about this and the solution was a firmware update. Below is the link to that thread.
I have updated my Galaxy S8 but I am still not able to get audio via the BT connected headset. Is there a specific patch I have to download to make this work?
Any info or feedback is appreciated.

Thanks for posting and welcome to Community!
I am sorry to hear that you are experiencing difficulty with your headphones, I would be more than happy to assist you further with this; could you please confirm if you have the QuietControl30 headphones? Has this issue only just occurred or are you using the phone/headphones for the first time? What troubleshooting other than updating have you tried?
I look forward to hearing from you!
