delay in sound events.

[Colin J Thomson]

Hi,

Does anyone notice the delay in the system sounds, for example if I scroll
through my desktops the sound event can take up to a second or more. If I
disable Pulse all seems fine.

F9 - kde-4.0.84

Is this a known problem before I go hunt around bugzilla.

Cheers

Colin

Well I think I have found the solution from the fedora list archives, I was
part of that thread and totally missed this :-(

Create a new file called /etc/asound.conf with the following
lines in it.

pcm.pulse {
    type pulse
}

ctl.pulse {
    type pulse
}

I will test further but so far all seems well, I hope this may help others.

Yes, I have noticed the delay, too. When using certain applications, like
kplayer, perhaps others, but not sure if only kde3 apps, pulseaudio always
crashes and phonon sound falls back to the driver for my sound card (not sure
if this means it is using straight alsa, or something else). It should be
noted that the delay only occurs when pulseaudio crashes and the fallback is
used. When pulseaudio is running, there is no sound delay when switching
windows.


Your pulseaudio solution is already contained in /etc/alsa/pulse-default.conf,
is it not?

OK, thanks for the info, at least I am not the only one to notice this,

Indeed you are right, after more tests the asound.conf I added did not seem to
help.

Shouldn't happen, but you should ensure you have all the related pulse bits
in place.

For example, do you have installed:
kde-settings-pulseaudio
asla-plugins-pulseaudio
xine-lib-pulseaudio
gstreamer-plugins-pulse

Thanks Rex, yes I did have all the Pulse files.

Strange thing is since downloading 4.0.85 (thanks for the packages) things
seem a little better with the sound, I'll see how things go during the
evening.. or maybe I am imagining it again :)

In 4.0.85, the sound problem persists: when changing windows, the sould is
either delayed or gets chopped off.

Yes I can confirm this now..

FYI tonight I have been trying to get to the bottom of why Kwin was sucking
a lot of my CPU. Relevant system details:
Nvidia system using Livna's packages, Desktop effects enabled just recently.

I have found that disabling VSync in System Settings > Desktop > Advanced has
fixed this and there seems to be a slight improvement in the sound delays and
far less chopping off of the events. I guess over the next few days I'll be
sure if it has helped.

Related to heavy CPU usage maybe? perhaps this could help others.

Cheers
