Question: Does this wrk with Mac?
Document: this item does not support mac os x perfectlythree volume keys does not work on my maccontrolled only speaker volume
I think its a very powerful device, but how bad is that Creative website doesn't have software or drivers for Mac. My Mac recognize it, but it doesn't work 100%, some functions don't work.
Is this a joke this one lacks Mac support? There is no one word about Mac on their site neither in the specs, nor in the system requirements description.It's a shame not supporting Mac OS X for such a device in 2012!
I am sure this is a great product. I have always loved Creative audio products, but this one is not Mac compatible and that little fact is not mentioned anywhere on the Amazon webpage. So please be aware of this before purchasing this item.
I was worried it wouldn't work without a mac driver, but seems to be plug and play, just changed the settings for input/output on my mac. I'm using this between a sound desk and my macbook and its dramatically improved the sound quality of mp3 playback from my mac through the PA system.
I was looking for an external soundcard to connect my internally amplified 2.0 speakers with my subwoofer on my macbook.This product did not work at all with Mac, let alone Windows. After failing to get anything but one channel of audio working on my mac, I switched to a Windows laptop.Guess what? It didn't work either, even with drivers installed.
I accidentally selected this item to review and then realized it was a product designed to work with Windows based PCs. After doing a little searching I did find that it could be made to work with a Mac and set it up with my Mac Mini (running OS X Lion). It seems to work fine. I have not done a detailed listening test, but for my casual listening I have heard no degradation in sound quality in using this product.
x-Fi supports at least EAX 3.0  andI think possibly 4.0 ,..and maybe even 5.0 . Why ?
works great but I di have some trouble playing through the line in input while the pc was hooked up , very low volume witch is a pain because I use it to play audio books from my phone AT WORK
works as advertised.Be sure to install the drivers from the setup disk to get the full benefits of this product.AlsoWhen using remote use the volume buttons in upper left corner to raise or lower volume.James :)
Answer: It does work with OSX as a USB passthrough.  Keep in mind OSX passthrough means you will need to use the volume control on the device since you will lose the keyboard (software) volume control.  This is the same loss of volume control for SPDIF(optical) and HDMI.
