音源を切り替えると、音声が聞こえるまでに遅延が発生します | Lifestyle® 18 Series II DVD home entertainment system

外部デジタルオーディオ機器では、音が聞こえるまでに最大で5秒かかることがあります。

If an expansion room has been given priority to a digital source (internal or external) that is being played simultaneously in the main room, the main room will not try to reacquire the digital audio signal in the expansion room if the expansion room source is switched or turned off. This behavior is designed to prevent any disturbance to the main room audio caused by actions in another room

To force the main room to reacquire the digital signal, switch to a different source and back or turn the main room off and on
