Hi Gerbils. Last month I got myself an MSI 990FXA-GD65 (GD65 for short) to replace my MSI 785GM-E65 (and E65 for short). The GD65 sports a Realtek ALC892 audio codec, which seems to be overwhelmingly popular these days with the newest boards. Looking at their respective pages on Realtek's website, however, I noticed that the ALC889 actually has better SNR than the ALC892, which is several dB lower. The ALC892 supports THX. Whether or not that offsets the lower SNR, I'm not sure.

Also, with the E65, I can plug my 2.1 speakers into just about any jack because the ALC889 supports jack retasking. The ALC892 supposedly also has this feature but I've noticed that with the bundled drivers, I can only plug my speakers into the default jack (top-middle). I downloaded Realtek's driver (2.70), which improved the situation by allowing me to plug my speakers into the top three jacks but not the bottom three. Unfortunately, I noticed that Skyrim is having trouble with a missing DLL file with the drivers I downloaded (missing X3DAudio1_7.dll). Not sure if it's caused by DirectX or Realtek's drivers or CCleaner removing important files, but I'm inclined to think the drivers I downloaded from Realtek may be missing this file. Unfortunately, the drivers that came with my board are a bit lacking in terms of jack detection. Any thoughts?
