Recientemente tuve la necesidad de realizar una reinstalación limpia de mi máquina y, en su mayor parte, todo está funcionando bien. Sin embargo, cuando intento conectar mis auriculares BT (Noga NG-55BT, auriculares BT genéricos), no puedo enviar ningún audio al dispositivo. Se registra muy bien y la máquina lo detecta, pero eso es todo.
Investigué problemas similares en este y otros sitios, intenté todo tipo de cosas y no tuve suerte.
