Hi!
I have built a retro-PC from an old Compaq Presario SR1100SF. Not a best choice but free. No ISA slots and bios is very limited.
Anyway I was wondering if it's possible to disable AdLib Emulation for CT4810 sound card under DOS. I have Windows 98SE/MS-DOS 7.10. I installed these drivers for CT4810 "Creative DOS Drivers for the AudioPCI and Creative versions of that card" http://vogonsdrivers.com/files/audiopci.zip. Drivers work fine but AdLib emulation gives me a headache. (I also tried to install Ensoniq drivers but couldn't get sound card initialized with them.) I don't know how to disable AdLib emulation. I have set synthvol to zero from C:\DOSDRV\SBMIXER.EXE but that doesn't always help. Some games set the volume to whatever number, eg. Realms of Chaos sets it to 121 right after I run that game. 127 is the max setting. If I choose Sound Blaster or Adlib sounds as music for this game it also causes picture to shake if I move around with the character. This does not happen if I choose Wave Blaster or General Midi as music option. Game runs smoothly if I do that.
I have also YMF724 audio card. Under DOS I use it only for FM because I haven't gotten sound blaster sounds to work with it. Sound Blaster sounds get me "DMA: Disable" and many of the options inside C:\DS-XG\setupds.exe are greyed out. Under Windows I can use Sound Blaster sounds for YMF724 in DOS games but not all games work under Windows Dos Box.
I use Realms of Chaos as an example again. (Allthough there are many games that have issues with AdLib emulation. Some games play music slower suddenly and then normal speed again.) The game works fine If I either avoid AdLib Emulation or use only YMF-724 for FM music while disabling CT4810 and choose AdLib or Sound Blaster as sound settings for music. Then I get only music and no sound effects. CT4810 drivers use AdLib Emulation so if I play this game with both sound cards enabled I hear double sounds for the music. FM by YMF724 sounds good but I hate Adlib Emulation sounds from CT4810.
If somebody knows how to disable AdLib Emulation, that would be really awesome. I have to add that some games play really well already. For example Dune2. Synthvol setting stays at zero and I only hear FM music by YMF724 and Sound Blaster sound effects by CT4810. However with some games I can hear faint Adlib Emulation music even with Synthvol set to zero. I tested Lemmings with only CT4810 and I heard very quiet music even after setting syntvol to zero so It definitely would be in my biggest interest to get rid of AdLib Emulation if at all possible. Of cource with Lemmings I can disable CT4810 and eliminate AdLib emulation this way and use only YMF724 for it because Lemmings has only FM music and FM sound effects anyway. But it's not possible with games that use both FM-music and digitized sound effects unless I am willing to sacrifice either one.
Help is needed!
