A few days ago I installed a Creative SB X-Fi Surround 5.1 box - a USB device that allows you to use good speakers from your laptop. At first I had no success at all, but following the steps at http://fedorasolved.org/Members/fenris02/pulseaudio-fixes-and-workarounds got me started. This is where the fun and games begins.
When I look at System Settings > Phonon, the number of devices that are listed varies enormously. I have seen about 10 on one occasion. Today there are 3, one of which is greyed out. I have no idea what causes the devices to be seen on some occasions but not on others. FWIW, the 5.1 system tops the list, the laptop's internal speakers are next, then the greyed out one is another configuration of the 5.1 system.
Then there's sound output from applications. On the occasion that all the devices were listed I had good sound from front and rear, left and right, no center and no bass. Today, from a CD + VLC I have good sterio sound from rear L and R - nothing from the other speakers. Amarok simply outputs through the center speaker. Clementine plays through the laptop's speakers.
I'm rather at a loss with this so any ideas you might have would be very welcome.

It seems that some change I made yesterday has made a difference - but not for the better. Now the Phonon page is systemsettings shows only PulseAudio as the output. Using the Test button, I get stereo sound from the rear speakers as before, but no application appears to be able to work with it. Every player I've tried is silent :-(
Do I really have to remove PA?

Hi,
maybe you want make this change:
resample-method = trivial
in /etc/pulse/daemon.conf
and reboot your machine , I have trouble restarting pulseaudio in F14 via killing the pulseaudio seems pulseaudio restart itself so executing start-pulseaudio-kde after the kill leaves sometimes some app without sound
another issue what phonon-backend do you use I was using using phonon-backend-vlc but because of:
https://bugs.kde.org/show_bug.cgi?id=264292#c4
after following the instructions in that comment and reboot, after oa few hours the problem came back following the instructions again and changing to phonon-backend-gstreamer and reboot again, and the problem was fixed or at least minimized
regards,
Gabriel

I don't think pulseaudio was properly installed, for some reason. After trying a few commands that I found on blogs I got a message saying that no pulseaudio daemon was running, and I couldn't find any way to get it. Rebooting didn't do it, so I assume that something was missing stopping it from initialising at bootup. I never say any phonon-anything backends offered - just xine, gstreamer and vlc.
I've removed PA altogether, and at least have sound from a single speaker now. I could really use some help to re-install PA properly this time. If I can get so far I can try your suggestions.
Thanks for answering

well, sometimes pulseaudio starts but crashes because consumes too much cpu, but changing the daemon.conf is a workaroud for that
sorry xine, gstreamer and vlc are fine, I was referring to the rpm packages names

only reinstall the pulseaudio rpms and yum reinstall /usr/bin/start-pulseaudio-kde , I never added or removed of pulseaudio related stuff from the Fedora 14cinstall via DVD

/usr/bin/start-pulseaudio-kde - now that's a name I don't recall seeing before. I'll give it a try and let you know what happens.

At one point I had some success in getting sound to work - not perfect, but not unbearable. Amarok played 2.5 tracks, then popped up a message saying that it could not work with the 5.1 soundcard. From that point on, it seems to have been broken. I know that my attempts to fix it, eventually to remove it and start again, may be part of the problem.
Anyway, I have now installed pulseaudio* alsa-plugins-pulseaudio kde- settings-pulseaudio pavucontrol pavumeter paprefs paman padevchooser. For start-pulseaudio-kde I'm told that no such package is available?
KMix shows only two instances of Internal Audio Analog Sterio on the Playback tab bit SB X-Fi 5.1 shows on the Capture tab. The Phonon page in System Settings shows only Internal Audio Analog Stereo as active. My 5.1 card is listed, but greyed out.
I heard no startup sound. Sounds from /usr/share/sounds don't play in Kaffeine. It looks as though I'm back to silence.

It seems that start-pulseaudio-kde comes from a larger package, as it must be already installed.

I don't know what I've done now, but after rebooting Dolphin starts with a blank grey page, and system monitor shows it in disk sleep. I see that 'disk sleep' every time something fails - my experiments with rsync across the LAN did the same thing, and I found no way but to reboot - but this time even rebooting doesn't cure it.
<A couple of minutes later>
Yikes! Loud startup music! All my devices are now visible in systemsettings, and dolphin is working again. As far as I know, all I did was try to persuade /etc/pulse/daemon.conf to write a debug-level logfile to /var/log/pulse.log (which it didn't) - how strange!
I wonder, dare I try amarok again? Tomorrow morning.

This rings a bell with me (no pun intended ;-) ). I have seen problems like this in the previous days where I get some programs with the D state on htop even although the CPUs are free (mostly). Like today morning when I was installing some program using yum that was in a disk sleep state, really weird.
Sometimes that also happens when kmix is taking lots of cpu. FWIW I am not sure these two are related.
This are just symptoms as I have not yet found a cause. After some time those problems disapear and the system works as intented.

When I was seeing the problem during my rsync experiments I tried leaving things alone for quite a long time, without them clearing. Since we don't have a clue at the moment as to the cause it's hard to do any serious troubleshooting.
I assume it has something to do with kio-slaves (something I know nothing about) because when that happens I can't run Dolphin or KWrite or a number of other applications. They all open with a blank grey screen. Working without a file manager is extremely slow ;-)

will you look the files sizes from
ls -la ~/.kde/share/apps/kmix/profiles/ if you have a file with a size from a 1Mb maybe you want to look at
https://bugs.kde.org/show_bug.cgi?id=264292
the above happens with a local pulseaudio sound server and using vlc as backend,
the workaround is at https://bugs.kde.org/show_bug.cgi?id=264292#c4 but maybe restarting the machine after moving the files is a good idea

There's only one file - -rw-rw-r--. 1 anne anne 492 Mar 12 16:20 PulseAudio.Playback_Devices.1.Controls.xml

I'm using the gstreamser backend - although I have tried the vlc backend sometimes, so it might have been a cause.

a shot in the dark well a possible explanation, to the above, when do you added that option, somewhat it slowed pulseaudio so it no used too much CPU so as result didnt get killed.

Could be. Do you think this line in dmesg is important?

Hi,
yeah start-pulseaudio-kde is a script, ran automatically at kde start session automatically without user intervention.
and the failure above MAYBE is (pulseaudio, phonon are obscure arts for me) in some machines, well in my machine, is impossible to kill and start again or simply restart pulseaudio, so in my computer any change in pulseaudio or phonon configuration I needed to reboot to get sound working.
so start-pulseaudio-kde only works for me, when runs automatically at kde session start, I know which other machines don't have that problem
in few words in , damn in the first email forgot to include this https://bugzilla.redhat.com/show_bug.cgi?id=566915#c28, again in few words pulseaudio crashes because wants to use too much CPU, so while pulseaudio is to be fixed you can use the workaround in https://bugzilla.redhat.com/show_bug.cgi?id=566915#c32
