i have cmake, mingw and vs2005 build environments that can target win98, but compiling even the oldest ver 1 build of fluidsynth i could find on sourceforge was a no-go. it would require fairly recent build tools manipulated to target win98 which i don't know is even possible anymore.

until recently, there weren't even winxp or non-sse2 precompiled binaries of any fluidsynth builds. a little bird had to go and request them.

With the glib libraries I link to in the previous post, I could successfully use the fluidsynth library that is provided with DosboxECE. It may just be a targeted build for libglib that is needed.

I've done a little more playing around with it too. DirectDraw and OpenGL don't seem to work for me, just surface render. MT-32 and Fluidsynth both work using the older glib.

Edit: This post is referencing using DosboxECE on Windows 98 Second Edition.

fluidsynth is a black, black hole. i just wasted another afternoon trying to get v1.1.2/11 to compile under mingw and vs2005. for starters, glib-2.16 is the minimum required version which is too new for win98. that's not so much a problem as the dsound.h header it wants. i've tried both directx 8 & 9 sdk headers modified for mingw, but apparently they're not new enough or who knows. for a solely command-line utility, fluidsynth has some asinine requirements.

dosbox ece actually compiles just fine for win98 without fluidsynth. i think i got it successfully built under mingw with all the remaining patches intact. attached is a binary for anyone who wants to investigate. it's useless to me unless it has some form of gm wavetable patch.

Hello, I use Dosbox-ECE (latest version) to play Screamer 2 and when I launch it the sound is noisy.

At start I have error messages about jack server and alsa....

I don't use jack server nor alsa but Pulseaudio.

If I disable midi, no more noisy sound.
I can not reproduce this issue with dosbox svn (compiled on my system).

What are the contents of your dosbox-test.conf? (specifically the midi section) Pulsaudio is a mixer that outputs to ALSA. So it is technically used.

Totally guessing without context, but I'd bet he issue is around Fluidsynth. I have had similar issues before. But need to see your config file setup.

EDIT:
Further, check out section 4.1 below, it has helped me in the past.
https://wiki.archlinux.org/title/PulseAudio/Troubleshooting

Thanks, I will make some tests.
Another things:
It could be interesting to post dosbox-ece code and releases on Github.
I found this Github page but it is not updated since july 2022:
https://github.com/realnc/dosbox-ece
AppImage will be a very interesting package format too for Linux users.

It's now updated to r4482.
