While playing around with Links - the Challenge of Golf and Life and Death 2 I noticed something which may be of interest regarding the adlib emulation. Both games offer the Realsound option to play digitized samples with the PC speaker. Both games work fine with speaker output (see also this post) but will produce garbled sound if you choose Adlib.

While OPL music works fine these two games seem to try to use the Adlib soundcard to play digital samples. I didn't know this was possible but even though it's totally distorted you can discern the music in the Links intro with Adlib configured as sound board. (Use the System menu to configure the sound board in the game).

I don't know if it is possible to realize the functionality of the Adlib card used by these games in Dosbox. I just wanted to point out (if not already known) this "flaw" in the Adlib emulation.
