I kind of asumed that people
looking to get sound working,
will first of all apply the SB
patch and only if this doesn't
help, they'll start looking at
an extensions such as the hack
to make doom working.
The fact that dosemu claims to
already have an SB support, must
no longer confuse people: not
that it is completely non-functional,
but the progs that can work with
it, can be counted by fingers.
Anyway I have added a note on the page.

Yes, unfortunately this is all my
patch can do for it. Most progs
must work well but not the ones
that uses DMA regs for synchronisation
instead of SB interrupts. The problem
is that for speed-up purposes dosemu
does DMA transferrs by a large blocks
rather than by single bytes, as a
real DMAC does. This confuses such
progs.
Make DMAC to be a separate thread
will solve the problem only partially:
OSS sound drivers doesn't like a
small transferrs.
So solution for that is not planned.
Use Linux ports of Doom instead.
One of such ports called "prboom"
have much better graphics than an
original one, so there is really
no reason to use dosemu for running
doom anymore.
