I edited the original description to add some more information, I hope nobody minds.
Also, please see bug #192888 regarding Flash. Adobe have released version 10 (beta) of the Flash plugin, and the solution proposed in this bug allows Flash's audio to work fine with PulseAudio without any other workarounds (even libflashsupport is unnecessary). ** Description changed: Steps to reproduce: Run both of these at the same time: gst-launch-0.10 audiotestsrc ! pulsesink gst-launch-0.10 audiotestsrc ! alsasink If your default sound device does not support hardware mixing, the second command will fail. ALSA cannot use the device while PulseAudio is using it, and this affects a lot of applications. Note that if you run the commands the other way around, alsalib will use dmix, and then so will pulseaudio, so there is not as much of a problem this way around (except for the fact that dmix and PA are doing the same job, and you can not control the ALSA-using apps' volumes and routing with PA.) Resolution: Follow http://pulseaudio.org/wiki/PerfectSetup#ALSAApplications i.e. install /etc/asound.conf with: pcm.pulse { type pulse } ctl.pulse { type pulse } pcm.!default { type pulse } ctl.!default { type pulse } + Then, install the package "libasound2-plugins", as it contains the + required "pcm_pulse" and "ctl_pulse" plugins. + Note, too, that there are some applications that fail with ALSA->Pulse: - SDL seems to hang with neverball, but that is fixed by installing the PulseAudio backend for SDL (libsdl1.2debian-pulseaudio), which will replace the default ALSA backend. + SDL* seems to hang with neverball, but that is fixed by installing the PulseAudio backend for SDL (libsdl1.2debian-pulseaudio), which will replace the default ALSA backend.
