O dispositivo Bluetooth alternando do Mavericks é suspenso a cada 3 segundos

Desde a atualização para o OSX Mavericks, meus dispositivos de áudio Bluetooth tiveram um problema chato. Quando nenhum som estiver sendo reproduzido através de um dispositivo Bluetooth conectado, o dispositivo produzirá um som de estalo a cada três segundos.

Eu segui os registros Bluetooth, e parece que o sistema está colocando o dispositivo no modo de segurança de energia a cada três segundos, e depois o retira novamente logo em seguida. De fato, as mudanças no estado correspondem exatamente aos pops.

Alguém tem alguma informação sobre como desativar esse "recurso"? O som produzido pelas mudanças no estado é incrivelmente irritante.

Caso eu esteja entendendo errado, siga os registros:

Parece que ninguém tem pistas sobre como responder isso para o Mavericks, e não consegui encontrar mais nada depois de procurar por algumas horas.

No lado positivo, isso é corrigido na visualização do desenvolvedor do Yosemite.
