[pulseaudio-discuss] Undurstand Asynchronous API :(
In a first discussion thread, I was looking for introspection to find and select outuput devices for a C++ DJ real-time-line with two output : main and headphone. Thanks for all your responses... I'm so looking to work with Asynchronous API ... (This is a new discussion thead about that.) ... but WAW ! It's so hard... :( 6 hours than I'm parsing documentation about... → http://0pointer.de/lennart/projects/pulseaudio/doxygen/async.html « What a ... » :) Please, is there some example about using Asynchronous API ? So way about C++ class/objet wrapping ? I've start somethings but nothing to be show here yet...

Hi, I installed the PPA, and the audio in Skype stopped working. There is no error messages, but I hear no notification sounds and no audio during calls. Sometimes, apparently at random times, I hear one of the notification sounds (login, end call). I must have triggered the playback of the sounds at some time before. In other programs, the sound works fine. Please say if there is any debug info that i can provide. Thanks for testing. Would it be possible for you two who had regressions to determine if it is patch 1, 1+2, or 3 that's causing the regression?

Re: [pulseaudio-discuss] Undurstand Asynchronous API :(
Ok, at this time, I've got result with Asynchronous API :) I've find some undestanding ways inside the pa source code...
