Setting openal32 to native restores sound to affected games. ./configure --with-openal issues no warnings concerning the presence or usability of libopenal development files. This is a good one. I double checked sound device usage. I did a "/etc/init.d/alsa-utils restart" and a "wineboot -k" between tests (also looked for rogue wine procs) and I still got the "Device or resource busy" message.
