I installed both vlc and mixxx. I can run a video on vlc, a youtube video and musescore all at the same time. My musescore is the same (or works when set the same). Anyway all three run. The audio from all three mix. SO far so good.
Now start mixxx... I already have jackdbus running and use jacksink as my pulse backend/device :) I know not very stock. Anyway, mixxx pretty much kills all the pulse sound. OK, mixxx is using jack directly and not trying to go through pulse audio at all. Pulse just looks like any other jack client and so the next thing is to try mixxx with another jack client... Hydrogen is handy and is not stopped by mixxx. Hmm. OK, lets see if /usr/bin/mixxx is a script that maybe runs pasuspender... No it is a binary. I would still say the problem is with Mixxx. I suspect (but don't know how to find out) that mixxx sends a suspend to pulseaudio when it attempts to get it's output set up... Either start jack or grab the alsa port... unfortunately it does not let go of it after it has gotten it's port (as it should... at least jackdbus does so) ** Package changed: pulseaudio (Ubuntu) => mixxx ** Project changed: mixxx => mixxx (Ubuntu) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1325752 Title: All apps become mute when certain apps are opened. Status in “mixxx” package in Ubuntu: Confirmed Bug description: 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. --- ApportVersion: 2.14.1-0ubuntu3.2 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: valentin 29817 F.... pulseaudio /dev/snd/pcmC1D0p: valentin 29817 F...m pulseaudio /dev/snd/controlC2: valentin 29817 F.... pulseaudio /dev/snd/controlC0: valentin 29817 F.... pulseaudio DistroRelease: Ubuntu 14.04 InstallationDate: Installed on 2014-03-28 (65 days ago) InstallationMedia: Ubuntu 14.04 LTS "Trusty Tahr" - Beta amd64 (20140326) NonfreeKernelModules: nvidia Package: pulseaudio 1:4.0-0ubuntu11 PackageArchitecture: amd64 ProcEnviron: LANGUAGE=fr_FR TERM=xterm PATH=(custom, no user) LANG=fr_FR.UTF-8 SHELL=/bin/bash ProcVersionSignature: Ubuntu 3.13.0-19.40-generic 3.13.6 PulseList: Error: command ['pacmd', 'list'] failed with exit code 1: Home directory not accessible: Permission denied No PulseAudio daemon running, or not running as session daemon.
