Hello,
I have a problem with PulseAudio on Ubuntu 14.04 LTS. (This problem is not
present for Ubuntu 12.04 LTS)
If you start a music, for example with VLC, a mp4 or a flac (or all
others files), or a video on Youtube with the Adobe flash player, or all
program who use PulseAudio.
If you start a program like Musescore or Mixxx, all others programs
become mute. It's a bug, because the volume indicate the program have a
volume of 100% but no sound.
If you exit Musescore or Mixxx, you can ear all others programs again.
(Instantly)
On Ubuntu 14.04 LTS the bugs is produced each time.
If you use pavucontrol, you can see the volume of VLC or others apps freezed
when Musescore is opened.
I haven't tested Mixxx on Ubuntu 12.04 LTS so I can't compare, but for
Musescore it's certain that the problem had appear on Ubuntu 14.04 LTS.
(I have installed all updates, and I use only apps on the official
repository of Ubuntu)
Version: pulseaudio 4.0
Thank you.
