Hi, can anybody say what this means: err:wave:DSDB_MapPrimary (0x403a8974): Could not map sound device for direct access (errno=5) What exactly went wrong? I think this is the source of my problem: Looks like Ultima Online tries to get special access to the sound hardware but has no luck. Then Wine tries to reduce the frament size in DSOUND_RecalcFormat (dsound_main.c: 955) and crashes there because fraglen becomes zerro in this loop: while (dsb->buflen % fraglen) fraglen -= sw; It tried Shogo but there was no problem with the sound (it was only the launcher). BTW: I disabled the sound and midi output of UO. Thanks -Josef Wegner
