F8. How to disable pulseaudio

[nigel henry]

Well I thought I'd got the sound sorted out. There are the usual problems like
setting indexing options for snd-usb-audio, and snd-bt87x
in /etc/modprobe.conf. Now pulseaudio has entered into the equation.

The sound was ok, but I've just been setting up mountpoints, and fstab entries
for a fixed harddrive (fat 32 partitions), and upon rebooting, and logging in
to KDE, I now get a window that I've often seen saying that the sound is
disabled.

I now try a music cd, and lo, and behold pulseaudio is claiming a permissions
problem.

Now I try and remove all the pulseaudio stuff. I've got my my audio sorted
without pulseaudio messing it up again, but trying to remove all the
pulseaudio components with yumex results in a lot of other stuff being
removed (supposed dependencies) . I'm having to write this freehand,as F8 is
on the other machine. This is what removing pulseaudio, also wants to remove
as deps.
akode
akode-pulseaudio
alsa-plugins-pulseaudio
gstreamer-plugins-pulse
kde-settings-pulseaudio
kdemultidedia (thats a bad one)
kdemultimedia-libs  (another bad one)
libflashsupport  (probably bad also)
pavucontrol  (no idea what that is)

OK. I cant remove pulseaudio without screwing up other sound stuff. I 've seen
a lot of posts about pulseaudio problems, but have trashed them as I didn't
seem to have a problem with it. Now I find myself in the same manure cart.

What is the easiest way to disable it, as it appears to be problematic??

Gratefull as always to get rid of this unwanted crap. I take that back, as I
suppose it's supposed to be doing something usefull, but isn't quite up to
the mark yet.

Nigel.

I use KDE and I found that in my case there was a simple way to make it all work.

All I did was create a new file called /etc/asound.conf with the following
lines in it.
pcm.pulse {
    type pulse
}

ctl.pulse {
    type pulse
}

Then logout and back in - in my case this all worked!

If this works for others also it should be included in the common f8 bugs page.

Mike, out of interest what sound Daemon have you set in KDE sound settings and
other settings like suspend, I read somewhere to use Enlightened and Pulse is
95% ok here, I am still playing around with it though.

I also added the asound.conf as you suggested thanks for that tip :)

Cheers

yum remove kde-settings-pulseaudio alsa-plugins-pulseaudio

should do the trick.

While pulseaudio upstream recommends that, we (fedora KDE SIG) found that
configuration (arts -> esd) very unreliable.

Hi Colin

I did not change anything from the defaults that were set up by the install.

How do I check which sound system is in KDE?

Certainly I did not change the contents of
~/.kde/share/config/kcmartsrc from the contents placed there by the install.

I know you can put esd in that file but I have not tried to do that.

Mike

Just take a look in the control center > sound & multimedia > sound system, I
would guess its set to auto with the suspend at 60secs,

Would be interesting to know the recommended config.

OK Rex, so what are the "Fedora KDE SIG" suggestions, would be most
interesting. As mentioned in a previous post I think the default settings
is "Auto" in the control center and suspend of 60secs.

Cheers

Thanks Rex. Problem solved with those 2 packages removed.

Thanks to you other folks who replied also.

Nigel.

That was the only rpm I removed (it took kde-settings-pulseaudio
with it).

I also found for SDL based games you need to unset the
SDL_AUDIODRIVER environment variable (or remove the
/etc/profile.d/SDL_pulseaudio_hack.* files).

So far, those two things have done it for me.

Yes, that's the default (for good reason). :)

Ok thanks,
One other thing I have noticed is a "lag" in the desktop (KDE) sound events
when running pulseaudio.
No pulseaudio switching desktops for example the sound event is instant, with
pulse there is a good 1 second lag/delay before the sound event plays.

I'll do more digging around over the weekend.

Yeah, I've noticed that too, but we've been focussing mostly on stability,
not performance.

What you can try is reducing the arts sound buffer (in
KControl->Sound&Multimedia->Sound System, Skip Prevention).  Be careful
though, reduce it too much, and pulseaudio stops working (for me, ymmv).
The lowest I've been able to make it safely was
23 milleseconds (4 fragments with 1024 bytes).
