You still need a patches to apply in
order to get the sound working.

At least dosamp works perfectly.

Either do we:)

Well, I am using an MPU-401 midi in many games
(all that support it), and they all work fine.
Even though it may require some leg-work to set
the things up for MPU usage on dosemu side.

If you are concerned about a sound support, the
open tasks are:
1. Software mixing framework to get adlib sound
and digital sound to work together;
2. Threading to run Adlib and DMA in a separate
threads to avoid a horrible lags and improve
performance (threading was already tried and
appeared to be somewhat problematic);
3. Output plugins for esd, arts, nas, alsa, you_name_it.
If you can pick up one of that tasks, that would
be great as I have a hard times now.

At least for the sound neither is required:)

That is *always* required:)

*Thanks* for following up on that. Otherwise my
reply could be different:)
