Hi @martin428 . This may be possible depending on the TV you have and provided the Buds are disconnected from any other device. Which TV do you have?
I do not have the pro but I have been able to connect the Buds2 via the Bluetooth on a 2017 Samsung Tv. Volume control did not seem to work via the Buds but was fine anyway. Volume was impressive, did work via the Tv remote.
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
My Device- S21 Ultra 5G ( SM-998B/DS ) CSC= BTU , 12GB/256GB
One Ui 4.0,Android 12 Official Version.
@martin428: Regarding adjusting the volume while connected to your TV, I feel like this would only be possible if you have assigned Volume Control as a Touch and Hold option on the Wearables app of your mobile device (Galaxy Wearables > Touch And Hold). If not, have you tried adjusting the volume using the TV remote?
