求救！Macbook出DAC冇聲

awckin

1）Amarra + Macbook internal speaker -->有聲
2）CDP ＋ DAC --> 有聲
3）Amarra + Macbook ＋ DAC --> 無聲

DAC認到唔同BIT RATE，但BOOT過機，check過sound output係DAC都無聲

請問有冇CHING知點可解決！！

看來問題在DAC 接收的sampling rate，
你的file格式是甚麼，甚麼sampling rate? DAC接收後顯示的是甚麼sampling rate?

邊部DAC？ 用乜野方式接駁？

如果各方面沒變，以前沒問題而現在有問題，
試試 remove了 Amarra後重新安裝，之前有一位師兄這樣就解決了問題。

根據現有資料，我幾相信其實係你沒有在「系統偏好設定」內的「聲音」選擇好你用來出聲的device，預設是內置speaker，你插了DAC有時是可以自動跳到DAC來output，有時係會short short地唔跳，要自己揀番的。
