VIA Envy
From Wikipedia, the free encyclopedia
The VIA Envy24 audio chipset series delivers true 24-bit sound for personal computers. While available as a discrete card, it is sold in greatest volume as an integrated solution for motherboards.
The Envy24 chipset was originally developed by IC Ensemble Inc (PCI vendor ID 1412, established 1997). The company was acquired by VIA in late 2000.
A total of 5 controllers exist in the Envy range. Ironically, since the demise of the SoundStorm audio solution, the VIA Envy has become an option as a replacement part for integrated audio on nVidia motherboards, along with cheaper Realtek offerings.
With the exception of the Envy24 controller, all other Envy chipsets lacks hardware 3D positional sound, which means CPU usage across various scenarios is noticeably higher than either SoundStorm or Audigy based solutions. VIA has stated it has no intention of implementing CPU offload in future hardware, due to the increased manufacturing costs.
