--- Comment #14 from William J May may.11b@runbox.com 2010-04-27 02:39:52 --- After further trial and error, HL2 runs perfectly when Wine sound driver is set to ALSA. Mandriva 2010 has a good implementation of PulseAudio, so switching from OSS (in winecfg) is as simple as a click for me.
Not 'fixed' just workaround for those who can use it.
