Maybe the ASM1083 adapter is damaged. I've tested a PLX based Amfeltec adapter and an Ali Express ASM1083 adapter and haven't any issues with SB lives in either.

I've read of some having issues with ASM1083 devices if they had PCI-E power saving features enabled maybe that's something to look into.

You need -12v rail for Sound Blasters to work, so cheap adapters won't work without additional modding.

This is the Ali Express adapter I used and it works great for sound Blaster live. I paid about $40 more than the already super expensive price for the Amfeltec because it had -12V and I'm not sure it made any difference.

Ali Express single PCI adapter $16.
Amfeltec dual PCI adapter $299

The cheap card had a molex cable which I did plug in???

Dothan Burger that adapter looks ok. Does it connect to a PCIE card with a USB cable?
Also what power adapter does it use? A floppy disk power connector?

The USB cable just carries the PCIE lanes minus the power to another PCIE adapter, like a mini PCIE or M.2 adapter. The Power is supplied by a standard 12V AC adapter.

This setup worked great for my Soundblaster live on a first gen Core i5 ITX board I'm working on.

I believe this is not true.

Asus H61M-K + SB Audigy 2 (SB0204) works fine with this cheap ASM1083-based PCIe-PCI adapter:

Of course you need to supply power with a floppy disk power connector.

Sorry to unearth a thread a several months after the last post, but I'm currently getting massive headaches getting an Audigy 2 ZS to work on AM5. Has anyone tried this on something like an X670/E motherboard and has a bridge confirmed working?

So far I tried:
- Pericom PI7C9X111SL - undetected (was detected on some of my slots in my previous, X570-based motherboard)
- PLX PEX8112 - detected but sound quiet and distorted, and card behaves erratically.

Anyone of you had better results with a specific adapter?

Wouldn't hurt to check voltages, and it never hurts to add another earth strap from card to the case to make sure it's good.

Maybe it's the AMD chipset giving you issues. I'm using the PLX PEX8112 with and Audigy and a PCI 3Com on an intel QM57 chipset.

It probably is, the Pericom-based adapter worked on an X570 motherboard just a few weeks ago, but I think some bridges (and some adapters using this or that bridge) may be more suited to modern platforms than others. After all, there is already a significant difference between the Pericom bridge and the PLX one, though even the PLX one doesn't yield satisfying results.

I'm not surprised that you got it working with Intel, it seems Intel-based motherboards are much better at dealing with legacy PCI. Unfortunately, I went the AMD route and it's too late to change course so if anyone got any good result on AM5, I'm all ears.
