For Windows XP retro gaming audio, the Sound Blaster Audigy 2 ZS is the better card — it runs hardware EAX 4.0 Advanced HD and has the broadest XP driver support — while the older Sound Blaster Live! 5.1 wins on price and Win9x driver maturity. If you're building an XP rig for EAX-era titles (2002–2005), get the Audigy 2 ZS; if you want authentic late-'90s/Win98 sound on a budget, the Live! 5.1 is the value pick. Both are still installable in 2026 and still sound great on period hardware.

The core difference: EAX generation and DSP
Both cards are real hardware-DSP sound cards, but a generation apart. The Live! 5.1 (EMU10K1) brought hardware EAX 1.0/2.0 and DirectSound3D acceleration to the mainstream in 1999 — it's the card that defined late-'90s positional audio in titles like Half-Life, Unreal Tournament, and Quake III. The Audigy 2 ZS (CA0102/EMU10K2) extends that to hardware EAX 3.0 and 4.0 Advanced HD, with higher SNR, 24-bit/192 kHz output, and lower-latency ASIO. For games built around EAX 3/4 — Doom 3, F.E.A.R., Thief: Deadly Shadows — the 2 ZS reproduces environmental reverb and occlusion the Live! simply can't.
At a glance
| Feature | Audigy 2 ZS | Live! 5.1 |
|---|---|---|
| Chipset | CA0102 (EMU10K2) | EMU10K1 |
| Hardware EAX | 1.0–4.0 Advanced HD | 1.0–2.0 |
| Best OS fit | Windows XP | Windows 98 SE / early XP |
| Output | 24-bit/192 kHz, 7.1 | 16-bit/48 kHz, 5.1 |
| ASIO latency | ~2–5 ms | higher / less consistent |

| Typical eBay price | ~$150–$180 | ~$20–$40 |
When the Audigy 2 ZS wins
If your build targets the EAX 3/4 era — roughly 2002 onward on Windows XP — the 2 ZS is the clear pick. You get hardware EAX 4.0 Advanced HD, cleaner output, low-latency ASIO for any DAW work on the same rig, and the deepest XP driver ecosystem (official Creative, kX Audio, and Daniel_K modded packs). For Doom 3's atmosphere or F.E.A.R.'s positional cues, the extra EAX generations are audible and worth the higher used price.
When the Live! 5.1 wins
For a Windows 98 SE build or a tight budget, the Live! 5.1 is the smart-money choice. It nails hardware EAX 1.0/2.0 — which covers the vast majority of late-'90s and early-2000s titles that ever used EAX — and its Win9x drivers are rock-solid and easy to source. At roughly a fifth of the 2 ZS's price, it delivers authentic period sound for the games most people actually play on a retro LAN rig. You give up EAX 3/4 and the higher SNR, neither of which matters for a Win98 Glide-era machine.
Driver notes for 2026
On Windows XP, the Audigy 2 ZS is the easier card to get fully accelerated: official Creative drivers work, and kX Audio unlocks ASIO and DSP routing. On Windows 98 SE, the Live! 5.1 is the more natural fit with mature stock drivers. Disable any onboard AC97 audio in the BIOS before installing either card to avoid IRQ conflicts, and confirm DirectSound hardware acceleration is enabled in dxdiag so EAX actually engages in-game.
Verdict
Match the card to the era you're building. Audigy 2 ZS for a Windows XP, EAX 3/4 rig where you want the best environmental audio and don't mind paying used-collector prices. Live! 5.1 for a Windows 98 SE or budget build where EAX 1/2 covers your library and the savings go toward the rest of the rig. Either way, pair it with a hardware-accelerated DirectSound setup and a period speaker set or headphones to hear what the DSP is actually doing.
Installation order and EAX verification
Whichever card you choose, the install sequence on period Windows is what makes EAX actually work. Disable onboard AC97 audio in the BIOS first — leaving it enabled is the most common cause of a card that installs but conflicts on IRQ or vanishes after a reboot. Seat the card in a PCI slot that isn't shared with the AGP slot per the motherboard's IRQ routing table, boot, and let Windows detect it before installing drivers. Install the period driver (official Creative for the era, or kX Audio on the Audigy 2 ZS for extra DSP routing), reboot, then open dxdiag's Sound page and confirm hardware acceleration is enabled.
To verify EAX is engaging rather than silently falling back to stereo, launch a known EAX title and toggle the in-game EAX/hardware-audio option — you should hear reverb tails and occlusion change in real time. If the option is greyed out or the effect doesn't change, hardware acceleration isn't active: re-check the BIOS, the slot, and that DirectSound hardware mixing is on. Period speakers or headphones matter here too — you can't judge positional audio on a laptop speaker.
Frequently asked questions
Is the Audigy 2 ZS worth the price premium over the Live! 5.1? For Windows XP and EAX 3/4-era games (Doom 3, F.E.A.R.), yes — it adds hardware EAX 4.0 Advanced HD, higher SNR, and low-latency ASIO. For Win98 and EAX 1/2 titles, the much cheaper Live! 5.1 is the better value.
Which card is better for Windows 98 SE? The Live! 5.1 — its Win9x drivers are mature and easy to source, and it handles the EAX 1.0/2.0 that late-'90s games used. The Audigy 2 ZS is geared toward Windows XP.
Can I still get drivers for these in 2026? Yes. The Audigy 2 ZS has official Creative XP drivers plus kX Audio; the Live! 5.1 has solid Win9x stock drivers. Disable onboard audio first to avoid conflicts.
