--- Comment #2 from Lee Marshall leeguy92@googlemail.com 2008-09-21 16:40:52 --- HAH, i've squashed it. for me anyway. I simply selected pulseaudio instead of ALSA and disabled driver emulation in the sound section of winecfg.
i discovered the problem by running: wine Wow.exe &> WowERR.txt
after the crash, WowERR.txt read: err:alsa:ALSA_XRUNRecovery underrun recovery failed. prepare failed: Input/output error ogram Files/Blizzard/WoW/World of Warcraft/Wow.exe: pcm_pulse.c:198: pulse_pointer: Assertion `pcm->stream' failed.
hope this works for others experiencing the issue. ive had the game running for around an hour, with no problems whatsoever. A note: i have to use DirectX mode. if i use opengl mode in the game, the map and all text on the screen disappears as soon as i enter a building.
