I can't recall ever having scratchy or screechy noises when I start any multimedia application. The only problem I had before I tweaked the PulseAudio settings was that XBMC did not produce any audio (although all other media players did), but that was resolved when I applied the procedure in my first post.

I did not need to do it, but the creation of /etc/asound.conf (plus the edit to /etc/pulse/default.pa already done by the SL developers) documented by micia in the thread Sabayon 5/GNOME/PulseAudio: flash plugin taking over audio has helped some people, and since my last post in this thread I have also implemented it. According to the article Why you should care about PulseAudio (and how to start doing it): "setting up ALSA to use PulseAudio through /etc/asound.conf, will account for 90% of the audio needs of a regular desktop Linux session."

I have not followed Phonon's development, but am confused by your statement that KDE users should use Phonon instead of PulseAudio, because I recently read an article by KDE and PulseAudio developer Colin Guthrie stating that he has given Phonon support for PulseAudio in the upcoming KDE 4.4.

I think the main problem with audio and several other things in Linux is that they are so complicated because they are very flexible, configurable and accommodate almost every possibility under the sun. If developers could hide the complexity and make the application work out of the box for the majority of users -- leaving the complicated tweaking for those who need to do it ('cause they want to stream music from a remote music server to a client in the bedroom, or whatever) -- then life would obviously be easier for the average user.

Biggest issue I've had with that card was making sure it was using analog output, not digital. for some reason digital is the default, even though in my experience analog is more popular. Feels like Word, Calibri and Times New Roman all over again! :cyclops:

Those noises may not be to often, maybe it's the hardware problem with my sound card or driver. One problem is how and to whom I report this if there is no error? The other problem is I would not like to touch anything unless I have to, especially when it comes to config files. In 90% cases sound works. I tried renaming /usr/bin/pulseaudio as suggested earlier, unfortunately Skype microphone doesn't seem to work with any settings. As long as my applications are not blocking each other, I'd stay with what I have. There are a number of fixes here that relate to SL5.0 and now on 5.1 some things have already been fixed. I don't have any problems with having the following apps running at the same time:
- Firefox with a web stream
- Amarok playing
- Skype microphone working
- I can watch movies in Kaffeine, all at the same time.

I guess we have to wait until developers clean up things and KDE team makes up their mind.

I agree, add to this that I have to check settings in a couple of places, for Skype I have to set option in:
1) KMix - at least a dozen of controls
2) System Settings Multimedia
3) in Skype

It's like too many apps are trying o take over the sound system.
And we are in the 21st century :shock:

Today I should do like in Star Trek Voyager:
"Computer - (Beeeep), disengage the sound system"
[computer] Sound system disengaged (end message)
" Computer - (beeeep), reinstall sound system"
[computer] Sound system reinstalled (end message)
"Computer - enable the sound system"
[ computer] Sound system is now enabled (end message)

Richard,

If you're still using PulseAudio, do try creating the file /etc/asound.conf as I mentioned in my previous post, as it does help. Actually I'm not sure why the SL developers didn't create it automatically upon installation; perhaps it was overlooked. Just create the file using KWrite or Nano as root user:

Code: Select all: pcm.pulse { type pulse } ctl.pulse { type pulse } pcm.!default { type pulse } ctl.!default { type pulse }

The other configuration file lines mentioned in the link I gave earlier should already be on your installation, which makes me think that /etc/asound.conf might have been overlooked. Anyway, try it if you are still using PulseAudio, as you can always just delete it afterwards if you want. PulseAudio is working fine for me, and I use all the applications you have mentioned (and more), so it is possible. My guess is that the scratchy noise problem is probably the audio driver for your sound card.

I tried some of the suggestions to get PulseAudio to work. I created an /etc/asound.conf file. That seemed to work for awhile. But now, once again, I am without sound.

I used to be able to do a horrible workaround which involved killing all processes using /dev/snd/*, unloading the sound kernel module, reloading it, and then starting my sound mix application of choice. That would then allow me to hear sound from an application. But for some reason, now when I try to kill all the sound processes, it just respawns more processes using /dev/snd/* under the username pulseaudio.

I hate to rant, but is there an easy way to get rid of pulseaudio for good? When I do eselect esd list, it only shows PulseAudio as a choice for sound system. I just want something that works out of the box, without tweaking, without kludgy workarounds. I've read articles that explain the history of oss, alsa, and pulseaudio. But even with the limitations of the first two, they seemed to produce at least SOME sound much more commonly than pulseaudio does.

Thanks.

I just use the ALSA driver for sound, it sounds better without pulseaudio on my system anyway. Pulseaudio has some nice features, but I won't be using it until the conflicts I've had with it are resolved.

This is the best computer advice I have seen in quite some time. I also got pulseaudio to work somewhat. It was kind of cool that I could play an mp3 file and a flash video at the same time and hear sound from both simultaneously. But that isn't really very useful to the average user. I just wanted to be able to play sound consistently and in all applications. For me, mp3's would play in vlc, but the sound level seemed to fluctuate even though the volume control wasn't changing. dragonplayer would not play sound at all with wmv videos. kmix was quite messed up, with the volume keys on my keyboard fighting pulseaudio. I would hit the volume down button, but the slider would keep going back up. I think I could mute the volume, but no luck with any other volume buttons. I even tried to switch the master channel in kmix, but that didn't help either.

Now that I used RParade's advice on how to easily kill pulseaudio, everything seems to work fine. The volume keys work fine. dragonplayer plays audio. And vlc doesn't alter the sound level arbitrarily.

pulseaudio is a good idea in theory. But it is overkill for most people. The developer can blame the distros for configuring it incorrectly. But that is part of the problem. Keep it simple. Then there won't be so many problems. People who work with professional audio should be the ones to have to mess around with difficult configurations since they already know a lot more about computer audio. Average Joe's like me just want it to work.

For me, sound was working perfectly before the recent update to KDE 4.4. At that point, the headphone port stopped working (M-audio revolution 5.1), and kmix wouldn't control the volume for anything except Amarok. I'm sure it's possible to make pulseaudio work, but I see no reason to when the system is perfect (for me) without it. I followed RParade's advice and got back the previous working sound system. It'll certainly do if there's no other solution, but if possible I'd like to find a way of disabling pulseaudio that will persist through updates and won't constantly bug me about dependencies. Does anyone know where it gets called to autostart?

Most of these issues are caused by various faulty configs we ship with, I hope to fix these in the run up to 5.2. Pulse is not buggy but rather the setup that is being at the moment is.

Kmix is also working, but please make sure you are using 4.4.0-r10, it required a reinstall here.

Also please file bugs with pulse versions / hardware so that we have a proper record of stuff rather than forum rants.

Pulse is working fine here on amd64 5.1+limbo and KDE 4.4.0 inc flash etc.

OK boys and girls, it seems many of you are still having a lot of trouble with audio. PulseAudio is working well for me (no issues at all), so I'm going to post my current configuration here in case it helps someone. Things have changed a bit with the new versions of PulseAudio packages that I installed since the first post of 29 October 2009 in this thread (see my post of 19 December 2009).

While I'm configuring ALSA or PulseAudio I have a mediaplayer playing. My laptop has a built-in microphone, but if it didn't I'd have a microphone plugged in too while configuring ALSA or PulseAudio. Also, I launch the PulseAudio Volume Meter (Playback) and PulseAudio Volume Meter (Recording) while I'm doing the configuration.

EDIT (March 31, 2010): Just a note for those of you with hardware including HDMI Audio who are still having trouble:

My new laptop has the following audio hardware:

Code: Select all: # lspci | grep Audio 00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 05) 01:00.1 Audio device: ATI Technologies Inc Redwood HDMI Audio [Radeon HD 5600 Series]

On the Configuration tab of the PulseAudio Volume Control application, I had to change the Profile of 'Redwood HDMI Audio [Radeon HD 5600] Series' to Off for audio to come out of the speakers (I left the Profile of 'Internal Audio' as 'Analog Stereo Duplex' as usual).

Hello Fitzcarraldo.

Thanks for your effort and that great guide.

I noted however that I have a little bit different packages on my systems.

Code: Select all: tlisiecki@lapek ~ $ eix -s pulseaudio [I] media-sound/pulseaudio Available versions: 0.9.15-r2 0.9.19 (~)0.9.21 (~)0.9.21.1 **9999[1] {(+)X (+)alsa (+)asyncns avahi bluetooth (+)caps dbus doc +glib gnome hal ipv6 jack libsamplerate lirc oss policykit system-wide tcpd test +udev} Installed versions: 0.9.21.1(11:28:44 PM 02/16/2010)(X alsa asyncns avahi bluetooth caps dbus glib hal ipv6 jack tcpd udev -doc -gnome -libsamplerate -lirc -oss -system-wide -test) Homepage: http://www.pulseaudio.org/ Description: A networked sound server with an advanced plugin system [1] "sabayon" /usr/local/portage/layman/sabayon [code] [/code] tlisiecki@lapek ~ $ eix -s kmix [D] kde-base/kmix Available versions: (4.3) 4.3.3 (~)4.3.4 (~)4.3.5 (4.4) (~)4.4.0 {alsa aqua debug +handbook kdeenablefinal kdeprefix pulseaudio} Installed versions: 4.4.0-r10(4.4)[1](10:41:57 PM 02/15/2010)(alsa handbook pulseaudio -aqua -debug -kdeenablefinal -kdeprefix) Homepage: http://www.kde.org/ Description: KDE mixer gui [1] "sabayon" /usr/local/portage/layman/sabayon tlisiecki@lapek ~ $

I believe that if you upgraded to pulseaudio-0.9.21.1 you would encounter my problems

However thanks to your guide I managed to straighten things up.

There are two things that have to be done together:

The first thing is that /etc/asound.conf must be present. Without it only amarok worked for me but neither firefox nor ie. smplayer.

The second thing: there was a difference between my default.pa and yours. It was "load-module module-alsa-sink". According to your config it should be commented out and so I did.

Code: Select all: ### Load audio drivers statically (it's probably better to not load ### these drivers manually, but instead use module-hal-detect -- ### see below -- for doing this automatically) # This should really be commented out! #load-module module-alsa-sink #load-module module-alsa-source device=hw:1,0 #load-module module-oss device="/dev/dsp" sink_name=output source_name=input #load-module module-oss-mmap device="/dev/dsp" sink_name=output source_name=input #load-module module-null-sink #load-module module-pipe-sink

My problems are gone now

however my device list does not look so good - I only have Internal Audio Analog Stereo and only that appears in Kmix.
