HD及 TrueHD音效問題

MM622

好多BLU-RAY碟電影選咗DTS HD, Dolby Digital HD或Dolby TrueHD後, 點解我部AV Amp(Onkyo TX-SR806)只顯示 dts或者係Dolby Digital而唔係 DTS HD或Dolby Digital TrueHD? 是否一定要用7.1隻喇叭至得?  小弟只用5.1對喇叭。
但係我明明記得睇過有d碟出過HD呢2個字喎........

可能你部藍光碟機或者播放器SET左去LPCM( 線性脈衝碼 )輸出 . 你試下SET返去bitstream( 位元流 )輸出 , 睇下出唔出到HD音效 ~

同埋睇下有冇開到secondary audio, 要off左佢先得

THX! 其實secondary audio係乜? 有乜作用?

有d藍光碟要開左secondary audio 先可以聽到bonus track 畫中畫入面d 聲，但係開左呢個secondary audio會解唔到dts truehd.

An additional setting option that may be available on your Blu-ray Disc player is "BD-Secondary Audio". Using this setting combines both the main high-resolution audio (Dolby TrueHD or DTS-HD Master Audio) signal with the secondary audio signal - However, if using this setting, the Blu-ray disc player will "downres" the Dolby TrueHD or DTS-HD to standard Dolby Digital or DTS in order to be able to squeeze both types of audio signals into the same bandwidth via bitstream. In this case your home theater receiver will recognize the signal as standard Dolby Digital and decode appropriately.

原來係咁, THX! 我打電話去Panasonic維修部向問佢饰師父都解釋唔到 secondary audio 用來做乜。
等我今晚試吓選 Bit Steam 同關咗Secondary Audio睇吓出唔出到HD音效先。

或者reset部BD機，去番出廠原本設定，通常原廠設定都會出到HD Audio d聲既

得咗! Bit Steam 本來已經開咗但BD-Video Secondary Audio 係On, Off咗佢就得了。但係唔知點解响隻碟個Setup 已經選咗DTS HD Master但 部Amp只係出咗‘Direct” 而唔係自動出DTS HD Master, 要响遙控器上面個音效:  Receiver --- > Movie /TV (Search) 選返DTS HD Master出黎, 試過幾隻碟都係咁...............唔明。
