不知各位先進有無碰到這種問題
INSPIRE 5.1 Digital5600接上Sound Blaster Live! 24bit
利用數位輸出到喇叭只聽的到兩聲道
不管怎麼調都不行
類比輸出則可以
有懷疑原因會不會是線性輸入\麥克風輸入\數位I/O插孔同一個位置造成
希望有高手能幫忙一下這個問題
謝謝

That's the way it is. You can only hear two channels with digital input, when you are not watching Doby Digital & DTS source.
5.1 in digital will only works when there are digital signals decoding from movies or digital audio like ape.
( You can only hear two channels because your source
file is two channel like most wave, mp3 files. )

Analog input is a different story. It just mimics 5.1 channels and separate the sound into those speakers.
( It resamples two channels sounds into a fake 5.1 sound like most of the amplifier recreate the surround effect. )

So, You can only hear true 5.1 digital sound by playing movies with AC3, DD or DTS decode.
However, you can turn on the surround sound if your speakers has a surround feature or
using ac3filter to resample the two channels 's movie into a fake 5.1 surround movie.

補充說明
光纖輸出數位訊號,如果是輸出DTS  DD AC3等,
是一條光纖就可以搞定5.1聲道。
只要你播放器使用SPDIF by pass給喇叭就OK了。

但是如果放MP3,看一般的影片,沒有DTS DD AC3音效的,
那光纖輸出只能PCM輸出兩聲道!
