Hi,
to see how the cygwin sound support works and to compare cygwin performance in
some cases I have created a patch for the xfree game rocks & diamond from
http://www.artsoft.org/rocksndiamonds to enable the game on cygwin/xfree.

Now it runs with limited sound support:

1. Stopping of musics does not react immediatly (need about 20-30 seconds to
stop).
2. Delay on playing sounds (you can verify it with tutorial level 000)
3. While playing sound there are some unexcepted noise
4. cygwin uses a fixed buffer size of 16384. r&d like to use a 512 byte buffer,
which cygwin does ignore.
   This causes delay in 1.

To get it running for yourself, download the unix 2.0.0 src and apply the
appended patch.

Have fun

Ralf
