The scope of this post is not to set up a complete DOSBOX environment for the Lemmings games. However, if you want sound and your configuration isn't giving you any, read on.

Looks like a helpful guide! I'd never known how to have a look at the Tandy version of Lemmings 1, so that's neat.
Something to note: If you're trying to run Lemmings 1 and can only get "FX" lower your CPU cycles in DOSBox below around 3000. For some reason that makes it work. I believe you can turn it back up after the game has started.
Just to mention that you can get Tandy music and sound without using the graphics of the Tandy machine. You simply have to set :
[speaker]
tandy=on
[sblaster]
oplmode=none
And there you go!

Um, that doesn't seem to work for Lemmings, at least my copy of it. It does work on ONML however.
Yup, sorry, I didn't specified much.

It only works for Oh no! More Lemmings and all Holiday Lemmings. I guess this is because those versions have less music (3 and 6) than the original Lemmings game (21).
It works for getting Holiday Lemmings and ONML! It's not the graphics I mind, anyways. It's the not having TGA sound.
