I did all your patches at that URL (sound + serial) and got:

i.e. the serial patches required "fuzzing" and the DPMI patch failed. Using
dosemu 1.0.2.1. What I am doing wrong?
And, btw, what do the serial patches do (do they make null-modem games work?)?

Why not? I used to be able to select "Sound Blaster Pro", but I can't
anymore in any of my games and this is reducing the sound quality in some
games.

I've had mixed results with your new patches. In general, the code seems to
have gotten slower but works better.
Here are some results of testing:
Program no sound patches original sound patches new sound
patches
(sb pro) (sb pro)
(sb or sb clone)
Jill of the Jungle no sound distorted
perfect (even better than win98!#)
Scream Tracker 3 locks up locks up
perfect
Wolfanstine 3D no sound no sound perfect #
Swiv3D no sound intro works perfect
Descent perfect stutters perfect
Warcraft 2 stutters horribly works perfect
Spitwad Willy no sound ? perfect
Count Down initial sound, lock up stutters,clicking
perfect,clicking
One Must Fall 2097 perfect music is too fast music
skips & stutters *
Liero no sound perfect sound stutters
*
Clyde's Adventure no sound partial partial
Need for Speed no sound no sound no sound
Shell Shock perfect no sound no sound *
Monster Bash no sound no sound no sound
Kiloblaster no sound no sound no sound
Clyde's Revenge no sound no sound bombs out
Mugen no sound dos4gw exception dos4gw
exception
Commander Keen 4 no sound no sound locks up :( *
Cosmo locks up locks up
locks up
(for Oliver Ob: with Stas' latest patches, Scream Tracker 3 works perfectly
if you use SET BLASTER=A220 I7 D1 T1 and it plays MODs very nicely)
The game, Count Down, seems to have this loud click every time someone
finishes talking.
I can't hear the music in any of the games above (except for OMF 2097 and
Swiv3D). This music is sb, not adlib.

Cheap (but decent-sounding) PCI sound cards such as the Creative vibra 128,
don't have MIDI support builtin. I wish dosemu could use TiMidity++ code or
the TiMidity++ ALSA sequencer to support those without a MIDI card (windows
does this via sound drivers but OSS is far too low-level). Perhaps ARTS (KDE
sound server) should be used since it's higher level and would support mixing?

I want adlib! :)

This may sound blunt but it still needs a lot of work.
I am, however, very, very appreciative of your efforts.
Playing DOS games properly is one of the few things that can't be done well
in Linux, at the moment and I'm glad to see that you are improving the sound
code (the other things that need a bit of fixing are the DPMI and X VESA
support).

I'll be looking foward to any more code that you can provide.
Please keep up the good work!
This email was typed while Scream Tracker 3 was playing MODs in dosemu in the
background :)
Thanks!
