This sounds like there may be something actually wrong with the card. You can try my SETYMF util (see the post signature) and tell me what happens with it.

I faced the same problem today with an ymf715b-s I just got. I tried to re-insert the card multiple times to no avail. Both setupsa and unisound were unable to detect it. Setupsa reported the same error you saw. I went on to test my other sound cards with unisound and returned back to the ymf715 at the end. I loosened metal bracket on card and moved it a little bit to allow the card to be inserted deeper into ISA slot. This time I got one "sb reset error" but also successful configuration at the same time (without "opl3 sax board not present") which suggested it's just a contact problem. I re-inserted the card again and everything was configured correctly by setupsa. I also tested unisound and it worked fine too. I re-inserted the card again just to verify the problem is gone and it worked fine. I tested multiple games with it to be sure.

With ymf715 I tend to get IRQ conflict with built-in USB controller so I need to reserve IRQ5 for ISA in BIOS setup. Run HWINFO and check if IRQ5, DMA1 are free.

I thought this ymf715 is a dead card but it got resurected in the end. I faced similar issues with another ymf719 I got. But once they start working they work reliably.

Hi! Thanks for the help I try everything but nothing. Finally I install ms dos 7.1 and a creative (sb emu) pci card but this message appears and don´t let me start any program or file. mmm so Now I have a different problem jajajaj

yeah maybe it´s something broken or no clue 🙁

Hey, maybe try using Tiido's advice before switching to a different issue altogether with that pci sound card. At least try to solve the issue which is the whole thread post is all about "which your thread is about your yamaha ISA sound card"

This is vague and unhelpful because I don't remember the details, but I've had this too. Not even any luck with Tiido's software. But one day it came good. Was it my system config? Different mobo? PEBKAC? I forget. But it ended up serving me flawlessly in a 386 system for a while. Don't give up on it.

(Thank you for attending my motivational speech.)

I´m trying since yesterday 😉 I don´t answer yet because i´m tryin to understand what to do because i´m level 0 in old pcs...and my english doesn´t help. (actually I can´t use any pci soundcard in my 486 because of compatibilty and my only chance its this yamaha isa soundcard...so I can´t give up yet)
