Windows 7: No sound after windows 7 installation

Windows 7 Professional
No sound after windows 7 installation

Hi Guys,

I really need some help. I only installed Windows 7 Professional which was previously Vista Business and now my audio output device is gone. No sound drivers. I installed RealTek drivers but didn't work. I went ahead to install the original C-Media PCI Audio Device for vista. The sound started working but then all other programs (internet explorer, windows media player, adobe 9 professional, windows media center, etc) stopped. Once I uninstalled the PCI driver then they work again.
Please, any suggestions to help me get my sound back without affecting other programs?

The sound card was manufactured by SIIG Inc (SoundWave 5.1 PCI). Anybody with information? I need to get my sound back. Please, help. Thanks.

If you went from Vista Business to Win 7 Pro I assume you had to do a complete new install, not an "in place upgrade" With a new install on many PC's, the install sequence is (1) Install Windows (2) Install (motherboard) chipset drivers (3) Install device drivers. One of the prime things the chipset drivers do is define what devices are on or attached to the motherboard. If you didn't install the motherboard chipset drivers (if it's applicable to this motherboard) that could be the problem. If there are chipset drivers, install them then install applicable OS sound drivers and it should work. If there are Win 7 specific drivers available use them, if not Vista drivers usually work.

I have a c-media based PCI card as well and the 'original 7 beta' drivers that were available for my brand of card also stopped apps from loading. (They will still work, but require elevated permissions which was a PITA)

Until there are better/proper drivers available for your card, try the Vista drivers.
