I'am new to linux. I'am under Ubuntu 18.04 and I have a bluetooth Headphone (Doqaus Care1). The pairing works fine and the sound is Ok until the headphone goes in power save (if there is no sound/music played, the headphone shuts down).
But when I turn it on, and play music again, it plays it in Mono.
I have to disconnect and reconnect it (in the bluetooth menu) to recover the stereo.
Thank you for your help
