People are clueless / The card is amazing 4 April 2013
By Kommando Kodiak - Published on
Verified Purchase
This soundcard has mixed reviews for a reason, because people have no clue about computers- they think by just plugging in the card into the motherboard they'll instantly have 100 times better sound, sorry folks it's a little more in depth than that.

The reason the clueless have had issues is a multipart reason and each case of a bad review is they haven't done a mixture of the following;

1) Bought a quality sound system or headset (usb headsets will gain nothing here so congrats on not doing research if you planned to use one of those) to use the card the headset and sound system must be either optical or analog

2) you must disable onboard audio, that is to say disabling the sound chip on your motherboard from the bios (F2/del w/e POST says to tap to get to the bios at start up) BEFORE YOU EVEN INSERT THE SOUND CARD INTO THE SYSTEM

3} uninstall all previous audio drivers BEFORE YOU EVEN INSERT THE SOUND CARD INTO THE SYSTEM

4) Disable NVidia high definition audio drivers BEFORE YOU EVEN INSERT THE SOUND CARD INTO THE SYSTEM

5) The six pin PCIE auxiliary power IS NOT OPTIONAL it is MANDATORY for proper operation of the soundcard

6) once you have done all of the above and started up the system you must update the soundcard by going to the makers website ( and downloading the latest drivers and running the update here's where a lot of people mess up as they do not read the prompts and because of the unusual nature of the update; You run the update restart and run it again to finish updating it people miss that second bit. You restart one final time and you're done updating it

7) With the card fully updated and installed properly you can now hook up your sound system/headset to it refer to the manual for port listings and remember that the optical port doubles as the analog side channel this is where improper surround sound setup is. Refer to manual for port labeling and online for color coding so you know which color jack goes into which port.

8) With it properly installed and your sound system/headset properly installed you can begin tweaking system settings this is something people forget about and start complain about bad sound after they had done everything else right. On your start bar you'll see the sound icon a speaker symbol with sound waves ))) right click it
from the popup menu select playback devices
from here you'll right click on your headset/sound system and select properties from the pop up menu that appears
A window will then appear that says headphone/speaker properties and it'll have tabs at the top of it you'll want to click the last tab on the right that says "advanced"
now you'll see something called default format for gamers you'll want 24 bit kHz as you don't want to over sample too much for games (some don't like it but you can always try 24 bit 192 kHz if you like its up to you) for your audiophiles/music listeners 24 bit 192 kHz movie people either one of those works.Just make sure your device supports what you set it to.

Do all of the above and you'll have the most amazing sound! I was beginning to get bored with my music it just wasn't doing it for me anymore. Now with the sound card I hear things in songs I never ever ever heard or even knew was in there backing vocals instruments etc its literally no joke like listening to your music for the first time all over again I absolutely love it. Gamers knowing EXACTLY which direction enemy fire/voices/footsteps/vehicle noise (ARMA anyone?) is awesome and really cleaves threat search time.

I use a Razer Tiamat 7.1 Headset which also got bad/mixed reviews, people are clueless, they don't change the audio settings (as above) to 24 bit sound install it right etc etc. Instead they down rate something because they're too ignorant to bother doing a web search or he'll doing something so revolutionary as reading the manual! The headset is amazing does 24 bit192 kHz has an excellent SNR and sound range if you want surround sound and a headset that's the one to get I'll be releasing a review/guide like this for it soon too.

I i want to clear up on more thing, some idiot whines about "no drivers for it in over a year" that flat out NEVER happened the card was release in april/may 2012 the driver releases are as follows #1 Version on 2012/05/24 #2 Version on 2012/07/10 #3 Version on 2013/03/25

Mind-Blowing Sound Quality 21 Feb. 2014
By natefish - Published on
Verified Purchase
I'll admit, I'm not an "audiophile." But I do appreciate good sound, especially when gaming and listening to music. I bought this card to replace an aging Soundblaster X-Fi Titanium card -- Not being impressed with recent offerings from Creative, I decided to give Asus a go, since everything else they make is awesome.

I'm not at all disappointed in this purchase. This card can actually push my Sennhesier PC 350SE headset. Games, music and movies all sound great with this card. Be sure to turn on the Dolby Home Theater software and pick the profile for what you're doing (also adjust the equalizer to your liking) and you'll be in heaven. This beats out my $800 Yamaha receiver with the same headphone plugged into it.

The primary feature that drove me to purchase this card, was the sound cancellation and it definitely delivers on its promise. I game in a very loud environment. I constantly have a fan blowing on me, in addition to a decently loud air conditioner about 10 feet from where I sit. I've been searching for about 2 years (since I started my Youtube channel) for a way to record my voice, without needing to edit out a crazy amount of background noise. The ROG Command feature does that. Even with a 30dB boost on the mic, there's a nearly inaudible amount of background noise.

If you have the budget and enjoy quality audio, or need some good noise cancellation for your mic, this is easily the card for you. Anyone who complains about the audio quality, either has a defective device, doesn't have it setup properly, or potentially has a bad/defective set of speakers/headphones.

Note; I did also see some of the reviews here complaining that the Dolby Home Theater software doesn't work on Windows 8.1. That must have been fixed, because I'm running 8.1 Pro 64-bit and it works perfectly

Awesome Card!!! 11 Jan. 2014
By ReighnDae - Published on
Verified Purchase
Bear with me as this might be a bit lengthy. I bought a new gaming rig in January 2013 which only had on board sound. :-( I immediately bought a Sound Blaster Zx from Creative Labs. It had decent sound and software for tweaking your sound to your liking but whenever I rebooted the computer I had to go into my playback devices and select the card as default. I saw this card on Amazon by accident. Read the reviews and decided this was gonna be my new sound card and of course my GF got it for me for X-Mas. The reviews I read were quite clear on installation. Remove and uninstall ALL other audio devices and drivers BEFORE you try to install this. Also, you will need to have a six pin power connector or two 4-pin molex plugs available for this card. Also this card is a little big, so make sure you have room. Another thing is to use the drivers from the Asus website not the disk. I did all this exactly on Windows 7 Home Premium 64bit and the card worked fantastic. The sound is amazing! After that I decided to start using Windows 8.1 64bit. Again, amazing performance from this card. It really embarrasses my Sound Blaster Zx. If you really have to have quality sound from your PC, this is the card. The software allows you to change a slew of settings to get the sound you want and then save multiple profiles. The software also includes Dolby Home Theater v4. There is nothing I can say negative about the card. I highly recommend it. Yeah its a little pricey, but its worth it. Just remember to follow the installation tips I covered.

Great product! Needs more effort effort by Asus to put solutions to problem out in the open! READ FOR DETAILS!! 10 Sept. 2013
By Dalton M - Published on

Alright admittedly this product is riddled with reviews about chirping, buzzing, and helicopter/motorcycle noises along with bad drivers. As far as I can tell the driver issue is relatively alright now if installed properly. Another reviewer has install instructions of turning off onboard audio disabling your graphics card hd audio drivers and then installing with the most up to date driver.

These instructions aren't wrong, but I still ended up with the noises mentioned above. This isn't the only audio card that has the issue and ways to troubleshoot explain the problem are very broad when typed into google. My problem was solved by Asus tech support. Shocker tech support wasn't bad, but it took me getting into that stupid chat online with tech support thing 5 times before getting someone worth having as tech support seeing as how I couldn't find a phone support on their page anymore.

Asus tech support is like any other once you get someone who knows the issue or actually knows how to get you the solution your problems dissolve leaving you wondering why it was so hard.

Now this was my solution to the problem if you're sure drivers aren't your issue. I could randomly hear the noise dissappear, so I know I was missing something and didn't think the card was defective.
1) Unplug your headset and plug it back in
2)Make sure all your surround sound levels and windows levels are maxed (for the headset not mic if your headset has one)
3)I use the Razer tiamat 7.1 and as such used the control box to turn the master volume to 1
4)Start a media file doesn't matter what, but I just played a song I liked and set it on repeat.
5) as the music plays with your headset not on your head, as this will hurt your ears, slowly turn your headset master volume up until you can hear the music clearly through the headset.
6) turn music off and you shouldn't hear the noise anymore

I'm chalking this up as being the system purging an residual energy/audio leftover in your system stuck in a buffer maybe on through the headset and/or breaking in the card and headset as my headset was brand new as well.

For the mic issue Razer headsets are famous for having control boxes that control everything about the headset and these settings just stack on top of window's settings. To get rid of the noise in my mic I set the windows mic volume to between 5 and 15 with the mic boost between 0 and 10db, but anything higher put out the noise. Then on the control box I could just turn the mic volume up and bam no noise.

Hopefully this will help a lot of people and my steps may not fit everyone's hardware, but if you're wanting a sound card you apparently need to be smarter than the tech and simple solutions to use it.

If none of this fixes your problem others believe interference from other onboard devices and bad usb grounding in the case. Defective products are possible as well.

Wanted to knock stars for the trouble, but it isn't the products fault such solutions aren't readily available beyond search for that one good tech support.

Edit: I happened upon the noise again, but I found it was the pass through cable on the headset box causing the issue. With the cable plugged into the control box that let sound pass-through to the my monitor plugged in noise, but unplugged no noise. The noise didn't persist through the cable into the monitor, but as long as the cable was plugged in the noise was in the headset.

ROG Asus Xonar Phoebus Review 28 April 2014
By Steven R. Jackson - Published on
Verified Purchase
This is an excellent sound card. The adaptor works great when using headphones and you have the ability to set up your speakers and environment as you desire. I use the optical out along with an amp as I am using some high end headphones and I find the card to work very well. Also, with the latest drivers, you can select, under games, several pre-sets which is nice. I do find the sound, even when listening to music to be very good. If you are strictly into music/movies, there may be better sound cards out there but this one directs most of its attention to gaming. I did have a creative card in my rig, but found this one to provide better sound for gaming. And some old reviews complain about the lack of current drivers, but they have current ones available. I checked out the ASUS site first and did some research first. Had no problems installing the card or the drivers. Everything worked great.
