I'm not sure which of these is the most probable issue, but considering user Soeuni managed to get both a YMF724 and CMI8738 working through an ASM1083 bridge on one motherboard while being unsuccessful with this same PCI bridge on another motherboard, I'm thinking the PCI Express bus has no access to port 388. The FM block is faulty on the PCI Express CMI8378-LX The ASM1083 is not letting anything through port 388ģ. The PCI Express buses in the test computers are not allowing anything through port 388 (I tried on a Lenovo ThinkCentre with a Core 2 Duo E8400 and an HP Workstation Z420 with a Sandy Bridge-E Xeon E5-1603)Ģ. This makes me think there are one of three issues at play here preventing OP元 from working:ġ. The PCI Express one was completely silent. With both CMI8738-LXes running at once, both with OP元 enabled via PeekPoke (verified with RWEverything as well) and with port 388 open, the only card that would put out FM sound was the PCI CMI8738-LX. Then I decided to try using one of my PCI CMI8738-LX cards to force port 388 open. Still, even with OP元 enabled, port 388 is still closed with the PCI Express CMI8738-LX. It turns out PeekPoke was actually writing to the proper registers inside the CMI8738-LX and what I was seeing with RWEverything was actually, according to the CMI8738 datasheet, the PCI configuration spaces.

Update on the PCI Express CMI8738-LX situation. This does, however, concern me for my upcoming Skylake Core i7 build as I would really like to have hardware OP元 working on that, but the motherboard I'm looking to buy (Gigabyte GA-Z170XP-SLI) uses the same ASM1083 bridge on its PCI slots, which may potentially prevent hardware OP元 from working on the PCI cards (this board has two PCI slots, though I would prefer to only use one because if I will go CrossFire in this thing, one of the PCI slots will be obstructed, and I need to have one slot occupied by my SoundBlaster Audigy 2, which I use regularly for audio sampling). The cards I got working that are plain PCI have this written on them.Īccording to the date codes, the chipset on the PCI Express card is older than the others, so I highly doubt the PCI Express card is lacking OP元.

It's like the CMI8738-LX is hiding behind the ASM1083 and is inaccessible.Īs for what model this is, I have no idea how to determine that.

For whatever reason, PeekPoke writes to the ASM1083 instead of the CMI8738-LX's FM enable bit. This one is a PCI Express version with an ASMedia ASM1083 PCI bridge. Problems can arise when your hardware device is too old or not supported any longer.It's a CMI8738-LX card, and I've gotten at least two of the plain PCI versions working with hardware OP元. This will help if you installed an incorrect or mismatched driver. Try to set a system restore point before installing a device driver. It is highly recommended to always use the most recent driver version available. At the end of the installation, restart your computer. Follow the instructions that the program shows you.
