Auzentech Prelude 7.1 (Source: Hardware Canucks)
EAX 5.0 and Dolby Digital Live on a single PCI sound card

Auzentech is set to release the first third-party Creative Labs X-Fi based sound card – the Prelude 7.1. The Prelude 7.1, announced last month, allows users to enjoy multi-channel EAX 5.0 positional audio without connecting four sets of audio cables. Auzentech licenses Dolby Digital Live multi-channel audio encoding technology to provide users single-cable convenience over S/PDIF.

The new Prelude 7.1 mates features previously found on the Auzentech X-Meridian with the Creative Labs X-Fi sound processor. Auzentech equips the Prelude 7.1 with a removable OPAmp on the front channels output of the sound card, unlike the X-Meridian’s four removable OPAmps. A LM4562NA is the default installed OPAmp on the Prelude 7.1.  

Auzentech pairs the Creative Labs X-Fi sound processor with two memory chips for 64MB of memory. AKM digital-to-analog convertors are installed on all eight audio channels, a step up from the Cirrus Logic DACs employed by Creative Labs. Other notable features of the Prelude 7.1 include audio headers, although it is unknown if they meet Creative Labs’ specifications.

Expect the Auzentech Prelude 7.1 to trickle into retail channels in the coming weeks.

Hm I have heard about this somewhere.

I am sure there will be workarounds. PCI can't be around forever.

Caching is a well established method to reducing impact of latencies. CPUs do it, HDDs do it.
Not to mention there're on board RAM on these soundcards

Sound cards need near real-time latency. You can't cache information that doesn't exist yet. Take for instance sound input processed by the CPU and sent back out through the output (very common in studio applications for instance). Latencies down into the milliseconds can be quite noticeable in these cases. Same goes for games which generate sounds real time. They need output as soon as possible. Caching isn't an option.
