Samsung Galaxy buds no media output

[89Gimmy89]

I have the samsung Galaxy Buds+ (SMR175). They worked fine till some days ago. 

Now they connect with different devices (my Samsung S22, my work A35, my laptop). Audio works fine just during the call mode. With any device if i try to reproduce any media sound (spotify, youtube, etc) the audio is mute in the buds. 

I have tried resetting from Wearable app, i have tried to open and close call with telephone or teams on the laptop, i have tried to remove the BT pairing and doing it again... this is driving me crazy... 

I have used other speakers to check they are working all fine... just the buds...

EDIT: while checking with my windows PC, i succeeded in listening some music while touching the HANDS FREE AG / STEREO settings. Then they started working with my phone too... 

After that when they automatically reconnected with my PC they started not working anymore with the telephone again...
