Summary: Bought this to troubleshoot some sound issues I was having with an older Creative Audigy 2 card and cleared up right away after installing. Downloaded drivers from website rather than using disc. Obviously, this isn't the highest quality sound card on the market so you audiophiles that are even looking at this, don't bother but for anyone that is looking for better than onboard sound at a low price, this is the sound card for you.
Pros: Low Price, 5.1, Easy to install, "decent" control software. Works with Win7 x64.
Summary: A great sound card for the price. I only ever use sound cards in my gaming desktops, but I never bother with the high-end cards because they don't provide any real benefit to the player. Great SnR, front panel detection is absolutely fantastic, and the price can't be denied. In this case, the card does it job well, but leaves a bit to be desired in the software driver front: Using Teamspeak and Mumble often, I need to monitor my own microphone feed to make sure that I'm...
Pros: - front panel detection, - cheap, - good sound, - headphone amp is handy, - low profile card means it doesn't completely block GPU fans
Summary: This is a very good card for the money. But, it did not serve my purpose. I bought this item to use the SPDIF to hook up my PC to my home theater system. Unfortunately, this card can only pass through signals via SPDIF which are already encoded to either Dolby or DTS. The analog out works well and so does the Dolby headphones. I would rate this card excellent for gaming use with a Dolby compatible headphones.
Summary: If you're a gamer or mid-range audiophile, it's probably the best ~$30 you can spend. Has hookups for your front panel and also acts as an amp for your stereo headphones. Software is alright, there are third party drivers that work, but I honestly haven't run into problems with the official drivers. The only major con I encountered was not being able to find the settings to power my stereo headphones.
Summary: I've been using the on-board audio on my Asus motherboard since my NLE PC was new three years ago. It's taken that long to nail down the cause of periodic Sony Vegas Pro crashes. The crashes have not appeared to be related to the sound card however, I finally realized the on-board audio isn't playing nice with the editing software. The Xonar seems to have cured many problems and my 5.1 speakers are 100% better. I thought they were just crummy speakers.
Summary: Had to replace the function of a failed on-board audio chip. Tried several USB sound decoders - all un-satisfactory. Finally went with this card for a relatively high-quality inexpensive solution. Very satisfied.
