IF you get them installed and happy at the same time, i'm quite certain that in multimedia settings you can only choose one primary output at a time. So when playing games you go in and choose your onboard, otherwise you set it to onboard.
Is the purpose to go out to two independent sets of speakers, or to adjust for quality as you go? Sticking with just 1 sound card and getting an audio switch box may be simpler.
land a card with jack sensing support and case front panel connections. not sure if x-fi will do that, but with the HD Audio codec, it 'senses' a change in the jack so if you plug in your headphones to the front panel connector, it will disable the rear connection entirely until you unplug the headphones and it goes back to normal
It is possible, with music and videos using J River Media Center, however it isn't possible with any games that I'm aware of
As a side note, you might be able to configure your headphone jack as your default sound device so the game outputs to that, and then use J River to playback music on the other sound card as it lets you pick your outputs. (Its their multi-zone playback feature)
Quote: This addon isnt cheap, but there are directions to make one if you google it. If you plug in your headphones, it will disable your other speaker outputs
rockbyter is half right. I have the Audigy 2 Zs Platinum bay and I have managed to configure it to send headphone output without disabling the speakers plugged into the back of my soundcard (be it Hifi, my TV or PC Surround speakers
Disable the onboard audio - it will be too much hassle having both audio devices installed. Then using your X-fi and the drive bay you can use headphones while having audio through speakers as well.
Once the bay is installed just go to Creative Audio Console (Start ->All Programs ->Creative -> Creative Audio Console. Then go to the Headphone detection tab and untick the option to Optimise 3d effects for heaphones when using headphones and to mute speakers upon headphone jack detection.
You can keep the first option enabled if you want, but if you do, everytime you insert your headphones the speaker setup will change to headphone, and sometimes the headphone 3D effects don't sound so good on external speakers.
The X-Fi Fatal1ty cards have an inline 10-pin proprietary connector on them. This is designed so you have to buy Creative's front audio console, that Rockbyter showed the link to. But there is a way around it, so you can plug your computer's front audio panel to the 10-pin connector. You can make or buy an adapter cable that plugs from an AC'97 or HD connector to the 10-pin proprietary connector.
