--- Comment #4 from hash HASH.DuOrden@gmail.com 2011-10-30 14:44:17 CDT --- Some changes. As I tried wine-1.3.31-172-g7df0245 I've noted that in winecfg one can now set audio defaults to any available from OSSv4 audio devices, and that reminded that in "Lord of the Rings Online" suffer from somewhat similar problem.
In "Lord of the Rings Online" there is built in team voice chat system, which is by the way TeamSpeak3, and when one uses OSSv4 he can't hear nor can say anything to his/her team mates. But if one goes in Sound settings and scroll down to bottom he/she will see that the selected audio devices is, in my case, "SB Audigy main (vmix)" and if one switch from that device for both in and out to, again in my case, "SB Audigy main", then team voice chat will start to work as it should.
So keeping that in mind I've tried to switch all entries in Audio Defaults for Hellgate:London from "SB Audigy main (vmix)" to "SB Audigy main" and now I have sound and music!
So this bug have now a workaround but it shows the person or persons who work on OSSv4 module for wine need at least some time try to use vmix'es.
