OK, i've been seeing a number of motherboards... mostly namely the Asus boards being more prominent with this new Realtek ALC HD audio chip which even Realtek's own website doesn't list a damn thing about... hell according to thier readme file for the drivers, don't list it as a supported product.. So i decided to get a motherboard down with it. First off: While initial i tried the drivers (updated version off asus's own support center right off the bat), I ended up downloading the latest realtek HD codec driver set for vista x64. Even thought it doesn't show it as supported, it installed fine and actually did provide the proper driver update and fully fuctional Realtek Manager gui. For features, it's pretty much identical to that of a ALC882/883/888 series realtek chipset, From what i can gather on it though, the chip is superiorer in it's quality aspects, a considerable improvement. However it doesn't have Anything Surround sound related in the digital area, or Dolby Digital LIVE! or DTS Connect for that matter, it DOES however include: DTS ULTRA PC From what it states, it allows anyone using a Stereo only set of speakers or headphones to produce a better then average surround sound. From my initial tests, it does alot better then the mostly "matrixed" or Virtual Surround sound i've heard previously on the other older realtek chipsets as well as other competeing onboard and add in cards. Definitely a plus for those using stereo only or headphones for that matter. Course it's all personal preference as well. Aside from that, that's about it. If you looking for better features, The ALC889a chipset is still probably a bit better, but the quality won't be quite as good as the 1200 here. Now i would expect that realtek will have a higherend 1200 series chip that includes a number of digital as well as analog bonuses such as Dolby Digital LIVE! or other such features. So lets sum it up: ALC1200 Latest drivers from Realtek.com.tw install and work perfectly. Probably one of the best Analog only Quality onboard audio chip at present. Lacking Digital (fiber/Coax)capabilities compared to the ALC889a New Feature for those using Stereo/2channel/Headphones. I approve of this chip. It's a good addition to realteks Onboard Audio solution.
