I had the exact same problem, “no audio at all from AirPods Pro 2 but a successful connection to TV” and discovered this thread. My TV would show connection to the AirPods, but no sound, despite the headphone volume showing 50% on the TV. For me, a few posts within this thread led me to my resolution after a lot of self trial and error.
Although, I am connecting to a Phillips smart Tv, and not a Samsung model.Hopefully though, as my symptoms were identical to others here, the below summary of actions taken that may help others experiencing the same issue.
1) The first thing I noticed before researching was that when first connecting to the TV the AirPods would connect with the “ - Find my” suffix as part of the device name. I just assumed that was just what was being broadcast by the AirPods Pro 2 to a non Apple device when connecting to them. I think it is a separate transmission broadcast on a different frequency that overshadows the audio connection. Earlier in this thread it is mentioned that turning off the “Find my” setting in the AirPods settings and then reconnecting them to the TV helps. I did this, and yes I able to get the TV connected to the AirPods Pro without the “Find my” suffix.
I did this but still no sound! My TV volume was still showing 50% headphone volume.
2) Further on in this thread it’s mentioned about lowering the volume slider on the TV to zero and back up again to get the sound. So I tried this but still nothing.
3) Then, again mentioned further above in the thread was about the Airpod volume itself via the stem. I tried this by moving up slightly and heard something very low so I thought I’m onto something here! I then tried increasing the volume on the TV via the remote, and although it increased on the slider, it didn’t increase the volume in my ears and still very quiet sound! So I continued with the slider volume on the stem of the AirPod itself. I did it about 4 or 5 times then got to a significantly increased volume. I then had to turn down the TV slider volume as it was too loud!! My TV goes to 60, and I’ve got in on 15, so only 25% volume which is adequate. AirPods volume is at maximum on the stem.
It appears that the Airpod volume defaults to zero when connected to a non Apple device, I assume for safety reasons. It is also independently adjustable from the TV headphone volume itself, i.e. both the AirPods and the TV volume can be adjusted to adjust overall headphone volume (in my case at least with my TV).
It has worked flawlessly for me since, no drops or deterioration, I can pause and restart play with audio fine, I can change sources without issue.
In summary do the following:-
1) Disable “Find my” setting to ensure correct device pairs to TV. Name shown should match name in Airpod settings on iPhone.
2) Ensure TV headphone audio volume is above Zero.
3) Increase the Airpod volume slider on the stem by sliding upwards a few times. Then adjust TV slider to suit.
I would like to say a big thanks to the other contributors on this thread that led me to work out what was going on in my individual case. Without them I would not have solved this! I can now enjoy the football in bed without disturbing my wife!
Hope this helps at least one other person with their issues. Good luck.
