Continuing my Windows 3.1 audio escapades, I am now trying to get the sound working under sbtype=sbpro1 (CT1330). (Setting opltype to dualopl2 with type sb16 and its associated drivers does not work - MIDI output is random/hissy/offkey)
There are two versions of the 3.1 SBPro1 files floating around out there:
SBPW31 - drivers are slightly smaller, so I assume this is the older version. I cannot get any sound at all in 3.1 using these.
SBPWU - larger and I assume later version. WAV output works in 3.1, but FM MIDI does not. The midi file itself will play without an error message, but I cannot hear anything.
Any ideas? I am speculating that there is a "latest and greatest" SBPFM.DRV out there somewhere that does work, but I don't know where it is. Or is this one of those fringe cases that has not been implemented in Dosbox? One possible clue - installing the mono SBFM.DRV does give MIDI sound with sbtype=sbpro1, but of course it is mono.
