HOWTO: PulseAudio Fixes & System-Wide Equalizer Support

[ktronicon5]

I am also using an ICE1712 card and having the same problems since I installed karmic. Volume control seems to work but is not routing audio properly. It lists a "dummy output" but i have no sound in any application unless i'm running the Jack server. Is there a fix for this, or else a way to rout everything through the jack server? (firefox and rhythmbox etc)?

The card is a multi-in/out Hoontech DSP24

$ pulseaudio
E: pid.c: Daemon already running.
E: main.c: pa_pid_file_create() failed.

no idea what that means; pretty new to all this.

After doing part A and setting up the equalizer, I got the equalizer to come up and act like it was working, but it didn't effect my sound at all. I had to go to sleep, and decided to finish getting it to work today.

I got home today and when I turned my computer on there was no sound. If I go into the pulseaudio volume control it comes up with the error E that you labeled, the daemon isn't running.

When I try to run pulseaudio this is what comes up:
tedward@Tedwardbuntu:~$ pulseaudio
E: socket-server.c: bind(): Address already in use
E: module.c: Failed to load module "module-esound-protocol-unix" (argument: ""): initialization failed.
E: main.c: Module load failed.
E: main.c: Failed to initialize daemon.

I don't quite know how to address this problem. I am running Karmic 64 bit

I had a problem where Flash would cause 95-100% CPU usage in Firefox and other browsers. The movie would first stop having sound then would freeze altogether. Closing the tab where the flash movie was playing would not help. Only restarting the browser helped.

The solution?

I had timidity installed, from before my upgrade to 9.10. Timidity steals the soundcard which produces problems. After removing timidity, the problem went away. Now I get 30-40% CPU and after the movie finishes playing, it drops to CPU usage before playing the movie!

For those having any PulseAudio problems, READ OVER THE KARMIC CAVEATS WIKI!

"I get a lot of flak from Ubuntu users, and I am pretty sure the vast
amount of it is undeserving and not my fault."

Even with pages and pages of manual fixes, there are still problems.
pulseaudio was advertised as plug-compatible with ALSA but it is
anything but.

Why the Ubuntu team persisted with this garbage setup over two releases
is incomprehensible. Why did they go with a radical change, in an LTS
release but not test it until too late. Then they persisted in the next
release. Even with the pages of manual config changes, there are still
numerous unresolved problems.

This to fix - what? Sound worked for me before 8.04..

Why is the registration process so cumbersome? You have to register
twice for some reason, and the Ubuntu confirmation email took about 10
minutes to arrive, contrary to the false claim that it "has been sent".

The equalizer is working on my system. Pulseaudio is working. However, I have to kill it before using Skype. Hell on earth emerges if I try to use Skype with Pulseaudio... it won't work properly, voice calls get echos, stuttering, lagging and loops. For everything serious, I'd use alsa.

But one question I have... no one could implement this mbeq LADSPA plugin directly with alsa? One could write another tutorial to remove pulseaudio and use EQ with alsa.

Suddenly my Songbird is returning the error:

mediacore error: autoaudiosink and alsasink elements are missing

How can I repair this? I am running Hardy - I started down the road of part A, but got the error

cannot stat /.pulse no such file or directory
cannot stat /.asound* no such file or directory
cannot stat /etc/asound.conf no such file or directory

any specific repairs for the mediacore error given?

in fact i cannot find an asound.conf file using a catfish search of the file system. I find an asoundconf bin that runs though.

I am running Karmic 9.10 64 bit and my sound is inoperable. When I boot up I have no sound. If I go to sound preferences I see I have a dummy output. I can fix that with a sudo modprobe snd-hda-intel (my builtin card on the mb) and then I get a stereo output. However this does not survive the next boot-up even if I do a sudo alsactl store.

I am completely stuck with this and suspect this is what is preventing me from setting up pulseaudio. Eventually, I want to set up 5.1 sound.

Any help would be appreciated.

I am running Karmic 9.10 64 bit and my sound is inoperable. When I boot up I have no sound. If I go to sound preferences I see I have a dummy output.

I am running exactly the same as above, and as well only have a dummy output... I've no sound now since I upgraded to 9.10 (abt a month). I've tried almost all troubleshooting ideas that I could find in this forum. This problem is VERY annoying! Please give some good advice... is there a conflict? Why will AudioPulse-Alsa not recognize my sound devices.

thanks.. nice tutorial

I can't get sound to come out of Kdenlive 0.7.6 on Kubuntu 9.10 Karmic.

1. My system-wide sound is OK, everything is still set to pulsaudio, but after doing part A of this tut I find that playing an AVI video has cracks in the audio, though plain mp3 files play fine.
2. Before doing part A, Kdenlive gave me an SDL error message. It didn't crash the program, and video has always played fine through Kdenlive, no matter what audio settings I choose within the program (I'm now set to pulse)
3. After following this tut, Kdenlive doesn't give me the error, but it also doesn't produce sound.
4. So far this means that after upgrading to Karmic, my video editing has been borked, and though Kdenlive functions wonderfully otherwise, without sound, I cannot do videos.

Thanks to anyone who might check this out and provide some help! A bug report has been filed, but I'm not 100% this applies to my situation.
