Well, I have had the most absurd experience with my NeoHE430. The nightly buzz is permanently gone - all from adding a sound card (M-Audio Revolution 5.1). I've read plenty of times that adding load can kill buzz in certain PSUs, but as my previous posts have elaborated, my buzzing was only at night. Now my computer is finally quiet. After about 2+ years of fiddling with various components (with lots of help from SPCR), I have finally reached a point where I can sit back and enjoy my silencing effort. Granted, I still hear some fan "whoosh" from the PSU, it is more than I ever expected to accomplish. I am forever indebted to this wonderful site. I will post pictures of my system in the gallery when I get the chance. Now to figure out why my Sage won't work when it wakes from hibernate... but that's for a different forum to discuss.
Finally someone I can ask some questions about their Revo 5.1. Do you intend to game? I have had my Revo for around 2 years and I have to say that I absolutely love it! Well, as long as I'm not playing games in Windows. Music is clear and defined even at almost inaudible levels and at very, very loud levels there's almost no sound coming out of the speakers.
I first noticed the problem with Need for Speed Underground 2 but have since dealt with it with every other game, too, BF2, Oblivion... What happens is that there is a really awful scratchy sound that comes out along with the game sound. It is unbearable. It does not happen ALL the time but almost all of the time. Sometimes it does not even happen, but it usually does. It seems to start randomly. The only solution is to turn off Sensaura in surround sound settings, and that was M-Audio's solution in their website. I'm using Klipsch Promedia 5.1 Ultra speakers but I get the sound with the speakers disconnected and only headphones, different headphones even. I've used it with different motherboards, CPUs, RAM, PSUs, even different home with different power company... it's the card. If I turn Sensaura off, however, I will lose some serious frames in some games. 'Tis not THAT bad of a problem, however, because music and movies sound FANTASTIC and I use headphones with the onboard audio for games.
I read somewhere that there were different versions of the card and that is why Newegg does not even call them Revolution 5.1
but some other name like M-AUDIO 9900-40906-00 5.1 Channels
. What I would like to know is whether perhaps newer revisions of the card don't have the problem and I was hoping you could help.
Congrats on finally getting happy with your computer noise, I am, too, mostly due to what I've learned at SPCR!
