Depuis la mise à jour vers OSX Mavericks, mes périphériques audio Bluetooth ont un problème ennuyeux. Lorsqu'aucun son n'est diffusé par un périphérique Bluetooth connecté, ce dernier émet un bruit sec toutes les trois secondes.
J'ai suivi les journaux Bluetooth, et il semble que le système mette l'appareil en mode d'alimentation sécurisée toutes les trois secondes, puis le fasse ressortir peu après. En effet, les changements d'état correspondent exactement aux pops.
Quelqu'un a-t-il des informations sur la façon de désactiver cette "fonctionnalité" ? Le bruit sec produit par les changements d'état est incroyablement gênant.
Au cas où je comprendrais mal, les logs suivent :
