--- Comment #6 from Maik Wagner wagnermaik@web.de --- Just tested with 1.6.1 on CentOS 6.5 and the login window shows up okay. Unfortunately I don't know where to make the change to ALSA but got the following in console output
ALSA lib pcm_pulse.c:995:(_snd_pcm_pulse_open) Unknown field handle_underrun err:winediag:AUDDRV_GetAudioEndpoint PulseAudio "default" -22 without handle_underrun. Audio may hang. Please upgrade to alsa_plugins >= 1.0.24
Probably need to do the update to >=1.0.24 but everything seems to be okay again. Thanks for your engangement in wine, it's a great help.
