Heya, Try this patch and tell me if it makes any difference: http://plan99.net/~mike/threadprio.patch You will need to run "autoheader; autoconf; ./configure;" then make and make install in the wineserver directory, and then mark wineserver suid root ... chmod +x `which wineserver` I'd be interested to know if this solves the DSound underruns for you in this specific case. Also which app are you wanting to use? thanks -mike _______________________________________________ wine-users mailing list wine-users@xxxxxxxxxx http://www.winehq.org/mailman/listinfo/wine-users
