There is fate feature #305888 (Disable Pulse Audio by default).
What are the reasons to disable PA by default? Since arts is gone, why should KDE4 be left without any sound server at all? Most sound cards do not support hardware mixing, this means you *need* a sound server to play audio from several sourced at once, e.g. playing music while wathcing some video on the web. Wouldn't a clean integration of a sound server like PA make sense?
When the sound card doesn't supports HW mixing ALSA uses dmix by default since a long time ago. There is no need for a sound server if the only thing you want is software mixing.
How can I check, whether dmix is correctly running? I just noticed, without sound server I was not able to listen to MP3 music and to e.g. KDE system sound at the same time... And when I used Skype I was not able to use a media player at the same time, so I guess I don't have a running dmix plugin?
About the dmix thing... no idea, it's supposed to work always automatically (note that OSS apps or ALSA apps using hw: or plughw: could block it). You will have to ask in the ALSA ML.
PA allows other useful things too, so one can use different volume settings for different audio sources. For example use low volume for system sound while wathcing some stuff on the web browser :-)
Yes, (when works) it also has a lower power consumption and the network transparency is nice to have. Per-application sound control is *the* thing that would make me vote for PulseAudio. But we need an app that supports the PA mixer API. Change KMix for pavucontrol isn't IMHO an option for KDE. I just looked to KMix... it links to libpulse-mainloop-glib and libpulse, but looking at the source (http://websvn.kde.org/trunk/KDE/kdemultimedia/kmix/mixer_pulse.cpp?view=mark...) the support doesn't seems to be very complete. And looking at the app, at Help->Hardware Information it says: Sound drivers supported: ALSA + OSS + PulseAudio Sound drivers used: ALSA ...but I see no way to change that to use PulseAudio. If KMix doesn't supports PulseAudio and there is no other *KDE* mixer app that supports it then IMHO PulseAudio is out of the question. -- To unsubscribe, e-mail: opensuse-kde+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kde+help@opensuse.org
