RESUBMIT: PATCH: DirectSound

[Johan Gill <johane@lysator.liu.se>]

This patch should be used instead. Now all devices are queried for 
dsound support.

Changelog: Only enumerate DirectSound devices if any sound device in the 
system supports the WINE implementation of DirectSound. I have also 
added some entries to the sample config file and changed the values of 
the "EmulDriver" key to "Y"/"N".

Fixes: Sound in the game "Riven" on systems with soundcards without mmap().
