On The Card
The Fortissimo 4 uses a version of the VIA Envy 24HT called the Vinyl. Marketing lingo is certainly full of surprises - it's hard to see what vinyl has to do with an integrated circuit soldered onto an electronic board.
VIA Vinyl Audio
The audio controller features a Wolfson WM8776 codec and a WM8766 for most of the digital/analog conversion. The WM8776 has two 24 bit analog/digital conversion channels up to 96 kHz and two digital/analog channels up to 192 kHz. The WM8766 adds six channels with the same characteristics for a total of eight output channels for output in up to 7.1 format.
