hi again,
i am on to something but i will need help with this.
it seems to be a speaker (the left one, built in).
today it is worse, just like a permanent morse code sequence.
i opened the "audio hardware setup" in the control panel, and if i turn to "OFF" the built in audio and then turn it back to "analog stereo duplex" (default), it stops, or nearly completely.
as soon as i try to watch a video, it starts all over again..
if i have the volume control open, the buttons just flick up and down (even though i have them all muted)

is it only that my speaker is going..?
is there a way to just turn sound off and not hear it ? (muting does not shut it off)
thanks.

This sounds like a Pulseaudio issue. Please logout of KDE, kill all instances of "pulseaudio" then remove ~/.pulse* and ~/.config/pulse/ from all user accounts on your system.

hi,
i am a bit of a beginner.
i know how to log out, but how do i "kill" all instances of pulseaudio ?
is it done using the konsole ?
what commands shall i type in ?
thanks

The following commands should do what is needed:

Code: Select all

killall pulseaudio
rm -rf ~/.config/pulse/
rm -rf ~/.pulse*

Ensure you do this at a failsafe terminal, or virtual terminal. Running them in Konsole may not be effective - as Pulseaudio might automatically respawn.

hmm, what are failsafe or virtual terminals ?
it didn't work on the konsole..

is the "RUN COMMAND" app good for it ?

logout of your KDE session
then to get to a virtual terminal alt+ctrl+F1
then at the prompt enter your account then when asked your password

hi,
i tried doing that.
logged out, and went into the virtual terminal.
for the first command, i got a "no process found"
for the other two, nothing.
then i checked in the system monitor, and there are two processes called pulseaudio.. does it make any sense ?
the morse sound continues.

pulseaudio may not be running if there is no desktop environment (KDE) running so no process would exist
the 2 rm commands will not provide feedback

there is normally only 1 pulse audio process running per user

you're using a laptop? what happens if you connect headphones, does it override the speakers and does it have the morse code sound?

yes, it is a laptop.
plugging the headphones, i only get the sound there, yes.

something to try - change your phonon backend
you have a choice of gstreamer or vlc, switch to the one not being used
you may have to install the packages
then restart KDE

hi,
i had to install the vlc.
then restarted and prefered it as a beckend.
but no change i am afraid.
thanks.

there is something i tried:
when the morse sound goes crazy / very fast and constant,
in phonon, i went to the hardware setup tab, and in the built in audio chose "OFF" in the profile.
then i turn it back to analog stereo duplex and the sound stops.
any ideas ?

no good ones but I would force a re-install all pulseaudio and phonon packages, not sure how to do that on Kubuntu but assume something like Muon -> search for _______ installed packages -> select all -> re-install
