Hi Eugen, hallo Dominik,
I think, I fixed it, i.e. possibly the connected cases of 586531. The 
main thread  was closing the audioinput device, while the "Media Patch" 
thread which pumps the data into the internet was still active. 
Consequently "Media Patch" switched to the silence device. This was left 
in current_device of audioinput-core.cpp, and it was used for the next 
call. Attached patch also sets internal_set_manager(desired_device); 
when the stream is started, i.e. when it is really needed. The patch 
fixes all my greyed audiobutton problems. Dominik, I just uploaded a new 
http://wwwuser.gwdg.de/~mrickma/ekiga/ekiga-setup-3.2.pre6-release.exe . 
Could you try it, please, and see how many of your issues get solved. 
The initial mute which you desribe is good one, I think. The lady on 
500 ekiga net starts babbling along immediately and what we hear is the 
time which Ekiga needs to get ready. It is better to dump the buffers 
than to have audio latency.
As your cases, Dominik, are so manyfold I also looked into Ekiga's 
audiooutput with respect to saving the desired device across calls. In 
priciple audioautput-core can be affected in the same way as audioinput. 
But at the moment and for me things go right, i.e. 
AudioOutputCore::stop() is called twice when a call finishes and thus 
the desired device is saved for sure. I guess the calls come from Ekiga 
main and a worker thread. But with threading one always knows best in 
the end, so I prepared an addional patch (attached ekiga_4outaudiodev). 
The corresponding download is 
http://wwwuser.gwdg.de/~mrickma/ekiga/ekiga-setup-3.2.pre6-release.exe.isitbetter 
. Does it resolve any remaining issues for you? For me it is not better.
Regards
Michael
