PCI Envy24HT-S

VIA Vinyl Audio is a collective term used by VIA Technologies for the company's audio solutions. These solutions consist of high-quality dedicated sound chips from the Envy24 series for sound cards as well as audio codecs based on the AC97 and HDA standards for integration on motherboards .

history

The sound solutions of the Californian company IC Ensemble were originally developed in the late 1990s. VIA acquired this company in 2000 for approximately $ 11 million. Since then, development has been continued under the name VIA Vinyl Audio.

Audio codecs

AC97 and HDA codecs are used on modern motherboards as a replacement for dedicated sound chips. However, they are inferior to a dedicated solution in terms of their capabilities and quality.
