标题: 请教除了889A，还有哪些板载声卡硬解双D？？
个人水平不高，想找块能支持硬解DTS和DOLBY的声卡，集成的都行，找来找去好象能够确定ALC889A能行，可是这个只有在技嘉的主板上才有，而且就这块声卡不同的原因，同类的主板价格要高上200元左右，所以想请教下还有哪些板载声卡能硬解DTS和DOLBY，不知道同是ALC的888和888S行不行？？？有没有用过的同仁能介绍下，还有没有其他板载声卡的可选择？？？

微星的也可以吧，好像就是888，有款785G—E45/65的板子，组HTPC的小板，音质不错的。

微星的E65是 889  是最顶级的集成声卡，比889A还要好一点点！不过貌似无法硬解DTS

偶就是技嘉790主板，集成ALC889A声卡。

等下个月5350显卡出来后就可以硬解双D了，而且硬解所有高清视频。

摘录一段给楼主看看The ALC885 used to be the high-end codec, and is still used by DFI for their mainstream, (with the ALC889 creeping in at the top end). It is fairly competent and is good enough for most uses with its >100dB SNR. The ALC882 is similar. The ALC888 (in many variants like ALC888S and so on) is the most common codec seen today. It's predecessor was the similar but slightly lower performance ALC883. It is OK, but falls short of the desired 100dB ADC/DAC SNR performance that enthusiastic samplers or music lovers want. MSI seem to have the ALC888 implimentation at its best, although that is the best of a mediocre job. The ALC889/889A is an upmarket ALC888 and easily meets the 100dB SNR. I suspect it is an upgraded/graded ALC888. The ALC889A is a Gigabyte designation. The ALC890 is another improved ALC888, but only used by Asrock and probably a rebadged ALC889. ASUS have a non-standard codec, the ALC1200. This is believed to be an ALC888S or T in drag. Since Gigabyte have their own "type", Asus had to have one too.   b9 x0 r7 l7 S- }

至于你说的硬解，官网上直接有http://www.realtek.com.tw/produc ... px?Langid=1&PNid=24&PFid=28&Level=5&Conn=4和http://www.realtek.com.tw/produc ... px?Langid=1&PFid=28&Level=5&Conn=4&ProdID=173其中889形容是“The ALC889 supports host audio from the Intel chipsets, and also from any other HDA compatible audio controller. With various software utilities like environment sound emulation, multiple-band and independent software equalizer, dynamic range compressor and expander, optional Dolby® Digital Live, Dolby® PCEE program and DTS® CONNECT™, the ALC889 provides the highest sound quality, providing an excellent entertainment package and game experience for PC users.

我只是知道我买手头的那块主板也标榜能硬解，不过一直也没有时间研究过，楼主是怎么搞的？装什么驱动？官方的驱动装完是认出芯片，但是感觉没有什么区别。终极解码之类播放也不知道是硬解还是软解。
