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

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....
    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!
    • UP...
    • 放大器? 功放自己带dts解码 ,而直接通过hdmI, 电视不带DTS解码。
    • need to install DTS codec
    • 有几个方面你要检查一下
      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。
      • ????? HDMI just take the SPD/IF signal, if your coxial or optical able to output 5.1 channel, HDMI does same thing.
        • 不尽然。

            • 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
        • 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
          • audio coaxial cable
            • 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.
              • vista可以选择哪个设备输出信号
    • 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。
