That games are too old and are using
an obsolete method of sound output -
direct DAC access.
Try the newer games (the ones that are
using DMA) and see if they are better.
Or try the mp3 player dosamp.
If that works better, then you can try
to adjust the DIRECT_WRITE_FREQ constant
in linux_sound.h and tune it so that your
old games to work better (sorry, I forgot
to add an option for that, so it is necessary
to change that constant in the source file).
But if even the DMA-enabled games sounds
poor, then there might be something with
the driver. See sound-usage.txt for the
description of some driver-specific hacks
and try playing with the related options.
If that fails, try ALSA (if possible) as
it is known to be compatible with dosemu
in most cases by providing an excellent OSS
emulation layer.
