Summary: Bought this to replace my Creative based Auzentech X-Fi Forte. Connections and installation was easy, plugged the front panels HD audio without hassle. Sound quality, it depend which use you intend to do. I find the audio different on some outputs. The sound I use on the speaker was too muffled on my speakers while it was too hissy on my headphones.
Summary: The sound quality on this sound is quite astonishing, but the drivers used to function this card is a relative let down in it entirety. The virtual 5.1 surround or the positional audio isn't very good and games sounded rather muddy. You're going to have to fiddle with options to get the right speakers to work and what I found to be most annoying was it does not auto-detect headphone input, which resulted in having to manually adjust to sound to the headphones.
Summary: So this card gives me sort of mixed feelings. On the one hand the sound quality is amazing. There's no arguing that. The only problem is that the power connection on it seems to be quite finnicky. For example, sometimes when I move something around in my case the power cable gets touched just a little bit, and when I restart my computer I get a message saying that the power is unplugged, when it clearly isnt.
Pros: Very good sound quality, and good driver utility
Summary: This sound card works, mostly. There's nothing seriously wrong with it, but I have a few concerns that reduce its value for me quite a bit... Most importantly, I can hear no difference in sound quality between this one and the old, crappy, integrated Realtek in my MSI P43 Neo-F motherboard. I believe the guys on techreport it does offer better quality, and yet for me, personally, there's no difference.
Summary: Got this card installed on a new system. Sound quality is outstanding.. the problem is the drivers are crap. For many EAX games you must disabled the GX mode of the card or you will not only experience constant CTD's you will also find the sound ends up looping and the only way to fix it is a hard reset of the machine.
Summary: I followed the earlier post and installed the vista drivers from the disc followed by installing the update from Asus but no sound. It took me a bit to figure out that I had to enable the card. My system was sending the audio out HDMI. To enable right click on the sound icon on the bottom of the system tray. Select playback devices. Right click on Speakers Asus Xonar and set to default. I then right clicked on the Nvidia and disabled it.
Summary: The board sounds great! Getting it to run was not at all straightforward. I have an ASUS motherboard with Windows 7 32-bit and used the onboard audio for quite a while. Getting the new software sorted out was not at all simple. Disabling onboard audio didn't stop SoundMAX from trying to start up at boot time and getting in the way of anything. I gave up on the install CD - it takes over the screen and hides message boxes that require replies.
Summary: The card is a solid card, I'll give it that. But like many Asus products I've used in the past, after a bit of use, I began to have issues with it. As of today, for some reason, my front right speaker has almost no volume. Two sets of speakers replicated the issue, and moving the jack from the front to rear or side had the speakers working perfectly, meaning that for some reason or another the card is sending the audio wrong to the right speaker. No idea why.
Summary: The performance of this card is definitely superb to any onboard card. Its low profile also means airflow can still be kept at a good level. Here's the bad part... Plugged the card in, downloaded the Windows 7 drivers beforehand. So Windows detects, click on setup to install the drivers, restart the computer. Boots fine, no sound, and programs don't load at all. So after looking at forums for about another 2 hours, I figured out the driver problem.
Pros: - Sound is much more clearer than onboard, - Low Profile, - Price (can find one for $70 after MIR)
Cons: - Drivers for Windows 7 are horrible, - Not colour coded
