如果你的HDMI没办法输出8 CHANNEL AUDIO,基本上可以肯定是你的电脑设置错拉

kevin_tor(KFC)

HDMI supports up to 8 channels of uncompressed audio at sample sizes of 16-bit, 20-bit, and 24-bit, with sample rates of 32 kHz, 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz, and 192 kHz.[19][44] HDMI also supports any IEC61937-compliant compressed audio stream, such as Dolby Digital and DTS, and up to 8 channels of one-bit DSD audio (used on Super Audio CDs) at rates up to four times that of Super Audio CD.[44] With version 1.3, HDMI supports lossless compressed audio streams Dolby TrueHD and DTS-HD Master Audio.[44]

枫下家园 / 家用电器 / 高清video播放问题请教.... -zwkzm(为什么呢); 2010-2-18 {283} (#5892210@0)
下载的高清video通过usb drive and wd media player和放大器在电视上播放时，能感觉到DTS听觉效果，但是从computer通过HDMI连到receiver再到电视后，音响效果不一样了， subwoofer没有任何声音，receiver也检测不到DTS效果。不知是否computer播放器不合适, 我用的是Media Player Classic.

谢谢指教！

放大器? 功放自己带dts解码，而直接通过hdmI，电视不带DTS解码。 -ysysning(豆泡果之樱桃果果); 2010-2-19 (#5892713@0)

有几个方面你要检查一下 -kevin_tor(KFC); 2010-2-20 {434} (#5894946@0)
1。片源。片子的声音是否是DTS的，可以用g-spot 去看一下声音是什么格式的
3。声卡。要把声卡的设置成 digital output pass through.
2。解码软件，下载k-lite codec pack, 换codec,在AC3的设置里面，输出选择as is，如果使用光纤，把use SPD/IF选上。

个人建议，从电脑到receiver最好用光纤。3 feet的光纤也就6~7块钱。

个人感觉，光纤输出相对独立一点，比较好troubleshooting,

HDMI有的时候很讨厌，尤其在你的电脑里面有不止一个HDMI输出接口的时候。
跟电脑硬件有关系（或许是驱动），很多电脑如果通过HDMI只能输出两声道。一般电脑都还带有同轴电缆或者光缆输出，那都是多声道输出。 -newnews1(wu); 2010-2-20 (#5895900@0)

????? HDMI just take the SPD/IF signal, if your coxial or optical able to output 5.1 channel, HDMI does same thing. -kevin_tor(KFC); 2010-2-22 (#5898507@0)

不尽然。 -newnews1(wu); 2010-2-22 (#5899797@0)

我知道HDMI支持多声道，我说的是有些电脑硬件（或者是驱动）是不支持这么多的 -newnews1(wu); 2010-2-25 (#5907190@0)

电脑有一个digital audio output接口，看上去象RCA接口，请问应该买什么样的cable，另一端应该是什么接头，连到receiver什么入口，谢谢 -zwkzm(为什么呢); 2010-2-23 (#5899922@0)

audio coaxial cable -coolmao(酷猫*Zensunni); 2010-2-23 (#5899927@0)

one more question, if my computer have both HDMI cable and Audio Coaxial cable connected to receiver, when I play HD video, can they all work at same time or all signal go through HDMI cable only. -zwkzm(为什么呢); 2010-2-23 (#5900024@0)

vista可以选择哪个设备输出信号 -kevin_tor(KFC); 2010-2-23 (#5900069@0)

你的电脑显卡是什么卡，A卡N卡，A卡要装个显卡的声音驱动，并在声卡设置里改成这个。HDMI好过光纤，能用HDMI当然用这个好。还有播放软件也要做相应设置，改成SPDIF输出才行，上网上搜一下了，会有更详细的方法。 -pika2005(淡盐); 2010-2-23 (#5901596@0)
