Hi, PLEASE NOTE: I will get to the point about this problem being related to PAX drivers, but please just let me go around the houses a little first, and explain some background on the issue. I have a problem with my Soundblaster X-Fi (product: SB0670) under Windows 7 Ultimate. I originally installed the 2.18.0015 driver from Creative's website (file: SBXF_PCDRV_LB_2_18_0015.exe). The driver installed without any problems, but upon the completion of the install, there is no sound from the device. Under the device properties, the device is working properly and no errors are displayed, but there is no sound from the device at all. When Windows 7 starts up, at the login screen, there is a little bit of a "pop" from the speakers, like it's trying to play something, but it can't. Upon video playback, all videos are running extremely slow visually, but still with no sound. Windows Media Player plays sound files and MP3's but it's as if the speakers are not plugged in or are turned off (don't worry - I checked ) I decided to restore to a previous image of my PC when I had Windows Vista Ultimate, and installed the device with the 2.18.0013 driver (file: SBXF_PCDRV_LB_2_18_0013.exe. This is because the 2.18.0015 driver is for Windows 7 ONLY. The driver works perfectly!!! Under Windows Vista, in combination with the 2.18.0013 driver, the sound is working and perfectly clear. I changed nothing physically with the hardware during the comparison. So I restored back to Windows 7 (because it's my preferred OS), and tried to install the 2.18.0013 driver, but this version of the driver doesn't recognise the operating system, so I can't use it So, I decided to completely uninstall all X-Fi drivers (in the registry too) and try PAX's latest 4.60 driver. Unfortunately, I'm having exactly the same problems as I did with 2.18.0015. Has anyone had similar problems with the SB0670 X-Fi? Yes, yes, I know it's an OEM (and therefore sucky) card, but if it works under Windows Vista perfectly, then why not Windows 7, with the latest drivers? Being honest, I'd prefer if the error was actually a driver install error, unrecognised device or operating system, as this no sound business is just infuriating!
