AC'97 normally doesn't work under DOS, as it has no support for that. What DOS you actually use, doesn't matter. Are you sure it was working at some point before?

Realtek AC97 won’t work under DOS / FreeDOS in an real way (there might be a few media applications that support it, but you won’t be getting Sound Blaster compatibility). I’d look to add a dos compatible sound card, see what you have in terms of isa or pci slots. A PC from 2003 should still support something like a Sound Blaster Live! PCI.

When using Win98 with Realtek AC97, most dos games should work with Sound Blaster compatible Sound when launched from within Win98.

Emmm... it was not quite like that.
When I installed Windows 98 the first time to the empty hard drive, of course here wasn't sound on DOS when I restarted in MS-DOS mode. But in Windows 98 in some old DOS games like a Wolfenstein 3D, Doom, Quake and many others there was a sound (Sound Blaster 16).
But when I installed under FreeDOS, here's no sound on old DOS games. Neither DOS, neither Windows 9x.

It's an Intel Celeron(R) 1.70GHz.

I don’t know anything about running win98 ontop of FreeDOS but in pure FreeDOS if you are setting up a dos compatible sound card you need to use the /sb switch on the emm386 emulation line in config.sys:

device=jemm386.exe /sb

Maybe win98 requires this as well?

I installed Windows 98 under FreeDOS from disk.

Emm, what about JEMM386? Yesterday I installed QEMM, because when I tried to play on DOS mode, here was error that hadn't enough memory to play this game.

I don't quite get what you did. When installing Win9x, it will overwrite whatever DOS you had installed before and use MS-DOS 7.1. It may detect FreeDOS and in the boot manager allows selecting it as an alternate OS, but you'll never run Win9x from FreeDOS. (if you managed to do somehow, it's not supposed to work anyway)

I'd go back to square one an ignore FreeDos all together and install win98se and use a sound card with dos support on its Dos cli. Use a boot disk with cdrom support from such as bootdisk.com or similar and do the install routine using that or from a directory on the hard drive.

I had everything a little wrong.
I installed FreeDOS and Windows 98 on the different drives.
FreeDOS is installed on C drive, and Windows 98 - on D.

Ok that makes a bit more sense. I don't see any advantage of FreeDos over MS Dos 7.1. A Dos compatible card will be the way to go though if you intend to run programs in plain MSDos or FreeDos. At least both drives will be fat32. AC'97 should cover the windows side of things.

You will never get sound in pure DOS on that machine. Only inside of Windows 98, as Win9x provides some SB Pro emulation for DOS programs.

I don't know if you're hoping to get a different answer from other people but you're not going to.

You will NEVER get sound in FreeDOS using this sound card, in DOS games that is. You have to use Windows 98 to take advantage of the SB Pro emulation.

Get a computer with ISA slots so you can use a real Sound Blaster or compatible.

Hello, I'm from Russia (Why I write here? Because I didn't find the suitable topic for this).
I have an old PC from 2003 that's out of the city, I installed here FreeDOS and under that OS - Windows 98.
I installed Realtek AC97 for sound. And it's working... but only on Windows 9x when I play games for this OS and use an apps. When I play old DOS games (on MS-DOS mode or without), I don't hear sound - only PC Speaker.
But when I first installed Windows 98 on this old PC (of course, without FreeDOS or another DOS - only formatted the hard drive with Acronis), here was sound in old DOS-games.

Hi, try this software https://sound-dos.ucoz.ru/

This is a modified version of the HXDOS-extender (2.17+) to work with the modern sound cards:
Intel-HDA, ICH/AC97, VIA82xx, ENS1371/1373, CMI 8338/8738.

Maybe this will help you.

It won't work, unless you are going to tell him to stub the WIN32 DOSBox and play games from DOSBox in real DOS. Why even suggest this for typical user? Many had already given the right answers.

Because he most likely only registered here to promote his site. It's obviously making money with casino ads.

I wish I had known this was a possibility before now. I gotta try this.
