Definitely a sound-card.

Download these Live CDs like Puppy Linux or Ubuntu and boot them.

It's a good way to test if the cards work and usually they tell you bit more about the card.

I googled this Yamaha chip, but not much came out of it. And as you said, it only has a single chip on the card. So not sure if it's very capable...

IMO the Live! is easier to use because drivers are readily available and it's a very popular card and well documented.

lo

further searching suggests it's a compumedia / c-media
cmi8738 or some clone of that called a sound pro or
whatever. it's likely not DS-XG although it pretends to be.

the best sign for me is the routing of the midi gameport
to the controller. it's as per the 8738 4 channel designs using
cmi8738/pci-sx and nothing like a YMF744B for example.

of course this could all be wrong

bye

It also looks like a generic Cmedia type card.

Are those (real) Yamaha PCI sound cards any good btw? I have one or 2 laying around, made by Diamond iirc. They have the blue-ish PCB

I had a couple of them, both Aopen models, one based on this same chipset, the 724 series and another on the later 744 chipset.

You can still find the OEM drivers here BTW:

Yamaha OEM Drivers.

Try booting into Linux, open a console and type lspci. That will show you every PCI device in your system, with names. Some distros (Puppy Linux, DSL) don't have the names database, so they will show only the PCI IDs (but you can google that IDs and find what kind of card is).

When I look closely to the chip, I realized something. The chip is YMH724, NOT YMF724. Is there any (real) Yamaha chip with YMH724 (not YMF724)?

On the Windows Device Manager, the card shows up as:
Y.M.H. SoundFusion(tm) YMH724 WDM Audio

after installing the driver on an unlabeled floppy (just a few files without an EXE to install, so I selected "Have Disk" on the device setup wizard). It seems this is not the original floppy but rather a copied floppy from a driver backup application.

hi

i honestly have no idea who Y.M.H. semiconductor corp. are
or if they are really yamaha or not but vendor id 1013 and
device 6005 which is probably what you have and is
also found in the file cwrwdm.inf is registered in linux
as:

vendor: 1013 ("Cirrus Logic"), device: 6005 ("Crystal CS4281 PCI Audio")

bye

EDIT:
PS.
the header of cwrwdm.inf says the followinging btw,
; CWRAUDIO.INF - Device description file for Windows 2000
; Plug-N-Play installation of the YAMAHA 724 driver files.
;
; Copyright (c) 1996-1999 Y.M.H. Semiconductor Corp.

so, all in all this chip is a bit of an enigma. 🤣

Thanks heaps for the trouble, downloaded! 😀

hi

regarding the DS-XG driver then i have two of those
cards and both have worked okay in windows but
but both perform differently in DOS mode if you
ever work out how to operate that via the protected
mode driver.

on one card the system locks up immediately loading
the DMA TSR and the other it seems to work however
the TSR is huge and most of the tech demos i tried
complained of either being in protected mode or
having not enough RAM so i gave up with them.

they do sound good in windows though playing midi
however an external MU-10 is probably a better option
for XG.

bye

Slightly off topic but when did that stop anyone...

The Yamaha PCI cards [mine's an SP-724] can give you FM Synth for DOS games [due to a built-in OPL3 or some such] as well as XG midi, though it may depend on exactly which card you have. Some people seem to have to use an internal SBLink cable to the motherboard for DOS sound, but on my A7M66 that doesn't seem to be necessary though I only play DOS games from within a 98 dos box.

I think it's not the fuller XG implementation you get on something like an DB50XG or SW60XG, but it still sounds good.

AFAIK you don't get A3D or EAX with these cards though I guess that's hardly surprising.

hi

the DS-XG sound bank is half that of the db50-xg / mu-10 but
many years ago i remember trying powerymf and i
am pretty sure it worked satisfactorily. i just searched
and the page is gone but someone has stuff up
here:

http://www.trancein.com/articles/power-ymf.php

there is also a larger sound bank there. whether it's worth
the effort or not depends on the individual of course.

good luck

Edit: Completely unrelated, I just can't believe how many posts I got here! 😳

Both chipset are from Yamaha
YMH724 Low End model this more to OEM PC
YMF724 High End Model
But Yamaha drop all YMH model

yamaha never produce any sound chips beginning with YMH, they are all faked(mostly from my country), can be reprinted from realtek/crystal/cmedia chips.
