mac can not trasnfer sound to a bluetooth speaker
Hello. I got a Macbook air 2020 and a Marshall Bluetooth speaker (Stockwell II) I've been using it without any problem. Suddenly a problem has started. Mac shows me that it is connected to the speaker, however, whenever I play music or videos via mac, there's no sound in the Bluetooth speaker. On the other side, the speaker works when I connect other devices there (my iPhone, different laptops, etc.) So clearly something happened to my Mac.
How can I fix it?
Thank you in advance.
MacBook Air 13″, macOS 12.2
