I've had this sound card in my audio parts bin for the longest time, and today I popped it into a system to record from and it did not get detected at all. No prompt at POST about a PnP card being detected and initialized and UNISOUND can't find a PnP card in the system. It appears to be dead. However when I took it out I noticed that the lower right side of the card, near the bracket, was uncharacteristically hot for a sound card. I am thinking something may have died there. A voltage regulator or a capacitor failed short maybe? What is an easy way to torubleshoot this card and figure out which component is bad?

I have quite a few more YMF719 cards but I'd rather be able to fix this if I can regardless. 😀 So yeah, paging experts like @Tiido @keropi and @marmes here 😁

See if SETYMF detects the card with /FORCEPNP option, if yes then EEPROM is corrupt and you can write a new one from SETYMF too.

But if is not detected the 33.8688MHz crystal should be checked and 78L05 voltage regulator (the little transistor looking thing) to see if it gives 5V output.

EDIT: The heat suggests that voltage reg or something nearby has shorted, there shouldn't be any such excessive heat.

I reinserted the card to try the /FORCEPNP option but this time around it got detected at POST as an OPL3-SA card, and UNISOUND reported properly initializing it. When I tried to rune DUNE though, it crashed after the Cryo logo, just before it tried to play sounds.. Interesting.

SETYMF reports no card found or corrupt EEPROM as you noted, and in the utility I can run the OPL3 and SB Pro tests, and get sound just fine. WSS causes a hard lockup. How can I fix the EEPROM then? 😀

EDIT: Found it in the Exit screen, did it. Card's name in POST PnP Init changed but behavior is the same..

EDIT2: Got it working now, after a second EEPROM re-write. YAY!

And now everything is working ? Or WSS tests still lock up ?

WSS still locks up but that is most probably a resource conflict issue. WSS is not needed for my purpose so I wont troubleshoot that 😅

I have the same Yamaha 719E-S sound card, it works well in DOS (music and sounds work).
In Windows it doesn't work, drivers are installed, no sound, can't start the device .

Is there any way to fix this via SETYMF?

Where can I find the original firmware for Yamaha 719E-S (EEPROM HT93LC66)?

Before running SETYMF, the contents of HT93LC66 were empty.

SETYMF can write a new EEPROM that should be enough to get things work in Windows. I can upload a Labway and one other YMF71x EEPROM dump tomorrow.

After flashing with the SETYMF program, the EEPROM contents became like this.

Windows drivers do not work, no sound.

I would still try and get to the bottom of the "gets hot" thing. Intermittent failures can be caused by voltage dips which can be caused by a faulty regulator and/or accompanying capacitors.

Here are a few dumps from some YMF71x cards. You may have to reverse the bit order in every 2 bytes for things to be compatible with your particular programmer. My TopMaxII expects reverse order compared to what YMF71x itself uses.

Tried all three flashings, the card did not work in Windows.

After that I tried flashing again with SETYMF and the sound card worked in Windows.

Hi,
I am facing the same issue with my YMF 719. The windows drivers are installed properly but no sound. Under Dos many games work although I am getting a WSS I/o error when I restart in DOS mode and/or run the setupsa.exe utility. Could you let me know how you managed to fix it. Below are the images of my card if it helps. Thanks .
