I'm complaining. But let me tell you this. I dug through the Wine alsa driver, the alsa pulse plugin and the PA sources. I now pretty much know how these three components interact and where the problems are. I simply arrived at a point where I wasn't willing to dig any deeper. I'm simply not ready to study the codebase any more. I've seen my share. Enough to be able to create a fairly precise bug report. So I wrote to this mailinglist and asked for help. I didn't demand that you fix the bugs. I just wanted some advice. And to that I didn't get any response. > I am not using wine myself, and haven't looked into fixing this.

The async handler was removed last summer, as part of the driver rewrite in a GSoC2007 project. And a lot other fixes also went into the Wine alsa driver since then. Most of the issues have already been fixed. The mixer code still may be a bit unclean, but that has nothing to do with the audio playback problems. If you know of any other outstanding issues in the Wine driver (apart from the _delay() misuse), please tell the Wine folks or me, I'll gladly forward the mail to the current maintainer. As the chances of including a native PA driver in Wine are zero, the focus is on improving the current Wine alsa driver and the alsa pulse plugin. That is what I'm trying to do. tom
