Ask hardware questions in Marvin. This forums is for DOS games.

Sorry for posting in the wrong place. Could an admin please move the topic to the appropriate place please?

Or if anyone can provide any insight into the matter I would be very grateful anyway 😀

Moved to Marvin.

Set it as follows:
SBPro I/O to 220
WSS I/O to 530
IRQ to 7 (disable LPT1 or move it to IRQ5)
WSS (Play) DMA to 0
WSS (Req) and SBPro DMA to 1

Alternatively, set WSS (Play) DMA to 1 and the SBPro DMA to Same as play (the important thin is to have SBPro DMA = 1).

Now, add the followin line to your AUTOEXEC.BAT, notice that the P330 part should only be included if your BIOS allows you to set an MPU401 port (if you set it to something other than 330, change the parameter to match, e.g. P300

1SET BLASTER=A220 I7 D1 [i]P330[/i] T6

Games in DOS will eiher take the values off that BLASTER variable or allow you to set them manually. Set your games to "Sound Blaster Pro" for both sound effects and music to the addresses set in the BIOS setup. If the games have an option for Windows Sound System you can try using that instead, as it offers 16-bit stereo playback at 44100Hz (the SBPro offers 8-bit stereo playback at 22050Hz), but the SBPro should be safer. Also, if the games offer multiple settings for SBPro, choose whatever says "newer", "2.0" or something that indicates the later revision.

Also, be more specific about what doesn't work. Sound effects and digital playback are somewhat independent, so try using games like Duke Nukem 3D/Constructor/Warcraft 2, which allows you to test each separately in their sound setup.

I am not sure how relevant this is to your situation, but it might be useful to check what the control address is. At least on my 4005CDS, I am able to adjust it (typically 538h), but the Yamaha setup program loves to insist 370h instead, which caused problems with SB digital audio.

Assuming the 220CS is PnP-compatible in BIOS, it may help to go to OPL3SA.ini (in your sound driver directory), adjust the address, IRQ, and DMA info there, and then also set Config_PnP or similar to 1. That has tended to work for me, even with 2 different DMAs for WSS (0 for play, 1 for recording plus all SB functions).

Do you have your OPL3SA driver loaded during DOS boot?

Hey everyone.
Thank you so much for all the replies! I have been away for a while but I was able to get it to work.
Basically I had to set things in the BIOS similar to what is described above by alexanrs and I had to add a line to autoexec.bat with SET BLASTER and use the same values that I had used in the BIOS (I also had to add T3 or T4 to have it compatible with other soundcards).
Anyway, I also discovered that some games needed adjustments at their own setup. All is running fine now. Thanks a bunch for the info!

Good to know... and yeah, I goofed, it should be T4 (Sound Blaster Pro II) instead of T6 (Sound Blaster 16)
