SOLVED Pulseaudio not connecting

[Sammiel]

I tried to change the setting in the pavucontrol, configuration or input or output. I was thing there is a better sound option. In place my volume control applet in the panel has disappeared, and if try to open the pavucontrol, it displays the error message
“Connection failed, Connection refused”


I think it is having the same problem.

pulseaudio
E: module-udev-detect.c: Failed to get card object.
E: module-ladspa-sink.c: Master sink not found
E: module.c: Failed to load  module "module-ladspa-sink" (argument: "sink_name=ladspa_output.mbeq_1197.mbeq master= plugin=mbeq_1197 label=mbeq control=0.0,0.0,0.0,0.0,0.0,-4.5,-10.0,-6.0,0.5,1.0,2.0,4.0,4.0,0.0,0.0"): initialization failed.
E: main.c: Module load failed.
E: main.c: Failed to initialize daemon.

I have also remove the timidity, but still pulseadio not working
Any clues related to this Pulseaudio not connecting?

I have installed pavdev applet, because my friend have suggest me to do the same. When I try to open the manager it display the message “failure: connection refused at the bottom”, and when I try to connect it, there is nothing from where I cannot connect it.

It is unable to see any sinks or the sources, no clients or the devices. Volume controls still opens up with the “Connection Failed: Connection refused”. According to me there must be a way so that I can reset the default input or output options which is causing the problem?

I think PulseAudio has trouble while detecting the sound card.

ALSA is detecting it or not. Just check the output of following code.

aplay -l

There must be at least card 0, may be more. If the first card listed is not shown as card 0, ALSA failed to initialize properly. If you are getting this then you have to do this.

sudo alsa force-reload

This will help you to if no sound cards are listed, after that check the output of the following code.

lspci

If the card appears there, then your card is a USB audio interface, and then check

lsusb

If card 0 is present then you can use following code

speaker-test -t wav -c 2 -D plughw:0

If you want that your PulseAudio work smoothly then you must follow the procedure which are given below:

1. First take the backup and after that delete previous configuration files:

$ mkdir ~/pulse-backup && cp -r ~/.pulse ~/.asound* /etc/asound.conf /etc/pulse -t ~/pulse-backup/ $ rm -r ~/.pulse ~/.asound* $ sudo rm /etc/asound.conf

2. Ensure that you have the essential PulseAudio libraries and configuration utilities software installed:

$ sudo apt-get install libasound2-plugins padevchooser libsdl1.2debian-pulseaudio 3.

Ensure the evil "libflashsupport" library is not installed:

$ sudo apt-get remove --purge libflashsupport flashplugin-nonfree-extrasound

4. If you are Karmic user skip this step. Open System then go to Preferences and then to Sound. Now in the devices section, you have to ensure that all "Sound playback" options are set to Autodetect. After that set the "Sound capture" item to "ALSA"

5. Now open the PulseAudio Volume Control application

$ pulseaudio & pavucontrol

6. Ensure that your sound card's PCM mixer is not muted or set to 0% volume (this appears to be a common bug in Intrepid and Jaunty):

$ alsamixer -Dhw

I get a somewhat different error
Code:
pulseaudio & pavucontrol

E: module.c: Failed to load  module "module-alsa-sink" (argument: "control = PCM "): initialization failed.

pulseaudio

It is because of the permissions of the virtual sound user space.

Removing or the changing of sound systems is not creating any effect – but removing pulse stopped assured programs from running audio.

While going to home I have changed some of the permissions related to .gvfs folder that was done during the use of sudo chmod / chown on my home folder

Finally I have to use the root login for fixing the problem
