timppu: I voted yes, albeit I understand why GOG doesn't necessarily want to do it. It would mean more support calls towards GOG when newbies set DOS game sound card IRQs, ports and DMAs to wrong values without any understanding of what they mean and what they should be, and it doesn't work at all anymore. GOG strives to offer a simpler "just click to play" also for DOS games, that has less probability for user errors.
Or even if the user selects the right values, there can still be issues, like in Win7 and Win8, if you select General MIDI music for Little Big Adventure (instead of the default Soundblaster/Adlib music), it will play far too loud compared to the sound effects, and you'd need special steps (adding extra MIDI volume level commands into DOSBox conf file) and maybe even third-party programs (BASSMIDI) to lower the General MIDI music volume to tolerable levels.
I presume that is the reason why they've set the music to poorer Soundblaster in LBA, as it works more uniform across different systems, than the superior General MIDI music.
And with many DOS games, the users would need either Munt (not fully legal due to the ROMs) or a real Roland MT-32/CM-32L unit anyway to get the correct, superior music. The Adlib/Soundblaster music always sounds pretty much correct, even if poorer, without any tinkering.
So I'm fine without as well, even though then it means extra steps for me to change it. As long as GOG doesn't remove any sound setup executables from games.
I agree, more headaches for tech support. Most of yesterdays hardware doesn't even exist anymore, the same goes for their respective drivers and operating systems. However it would be nice if dosbox had support for SoundBlaster 32 awe.
