View Full Version : Xonar Phoebus not detected !!!

12-28-2012, 09:14 AM
So I received my Xonar Phoebus in the mail today and I disabled on board audio in BIOS, uninstalled Realtek drivers and plugged the card into my rig and in that order. On restart, the card isn't detected. Tried going to device manager and scanning for hardware with no luck. The sound card has power, indicated by the glowing logo and the lighting on the rear connectors.

Here's my config.

i5-3570K, Seasonic X-1050 Watt PSU, Asus Maximus V Formula mobo, 2x 7970 dual Crossfire in top two PCIe x16 slots, Running a clean install of Windows 8 64bit. The Xonar Phoebus is in the topmost PCIe x4 slot. However I've tried removing the GPU's and using the sound card in another PCIe x1 and x16 lane and the situation is still the same card is powered up but not detected. Have tried switching PSU cables also, no change.

Can someone please help ???

UPDATE : I downloaded the latest WHQL Win 8 drivers and installed them regardless of what Device manager or Speccy told me. Got an error during installation "Xonar Phoebus needs additional Power" but continued with installation anyway, reboot, enabled HD Audio in BIOS and now seems all is in order.

Feel like an idiot now but posted here anyway. Mods may sticky / close or shift this elsewhere. Thank you.

If you do indeed have the "same exact problem" then the update AloneQuotient posted should solve the issue. Otherwise please post an accurate list of your system components and operating system used along with a detailed description of the issue and the steps taken to resolve it.

It sounds like the card is the issue, if it's not being detected in multiple slots. (A giveaway of sorts: on a cold boot, you should be able to hear a loud single click from the card if it's being detected properly. If you don't hear that, something's definitely wrong.) The only other possibility would be to drop it in a second PC, but of course everybody can't do that...
