Hum, I have in priority repported the bug for pulseaudio and musescore. Look, I use kazam (beautiful version of this app for Ubuntu 14.04 LTS :) ) to show the bug in screencast.
On the vidéo, you can see musescore be immediately closed, but it's not that, look the timer on VLC, the time move in the future. In reality: I have start the screencast, and when I opened musescore, the sound was mute. In pavu control, I have say the sound appears to be freezed. So, kazam is freezed when musescore is opened, because he will record the sound and the sound is freezed. To test, I had take several screencast. I have uploaded 2 screencast. On the 2 screencast I do the same thing, but, on the first Kazam record the sound, on the second Kazam doesn't record the sound. You can show that Kazam is freezed when he record the sound when musescore or mixxx is opened. (on the vidéo, it's like the video was cut) And when he doesn't record the sound, you can show all the screencast. Theses screencast are the demonstration of the bug ;) With sound recording, first screencast: http://dl.smglive.org/Crone123/PulseAudio/With-Sound.mp4 Without sound recording, second screencast: dl.smglive.org/Crone123/PulseAudio/Without-Sound.mp4 I think the bug affect Pulseaudio and not only mixxx/musescore ;) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1325752 Title: All apps become mute when certain apps are opened.
