Pulse audio problem

[piùbelloincorsa]

Hello everyone, I recently installed Kubuntu 18.04.1 LTS, after making the updates, wanting to improve the audio, I followed the guides indicated on the internet to activate the equalizer, similar to that reported in this forum, in another discussion. At the time of launching the command 'qpaeq', in response I get:

There was an error importing needed libraries
Make sure you have qt5 and dbus-python installed
The error that occured was:
No module named pyqt5

I tried to install the pyqt5 module but it still gives me the same error.

Can you have a clear and complete guide to what you need to install first and the procedure that activates after the equalizer? Thank you.

Lets try to solve your dependency problem first. You might first want to make sure that you're starting with a clean slate. Try running this to clear out any packages that may be left half-installed:

sudo dpkg --configure -a
sudo apt install -f

Once that is done and assuming it runs without errors, try installing pyqt5 again.

[vinnywright]

what you want to make sure you have are (and thay should all be installed by default)
python3-pyqt5
python3-dbus.mainloop.pyqt5
python-pyqt5

do remember you must load the modules

pactl load-module module-equalizer-sink

and

pactl load-module module-dbus-protocol

see link in the last post to see where to put that if you want them loaded at boot .

to whatthefunk:

Thanks, but I had already installed pyQt5 without problems.

I executed those commands and they did not have to solve any problem of that kind.

to vinnywright:

Thanks, I had already read the guide of that link but it did not solve anything.

I checked the existence of those packages that obviously are already installed.

Before running 'qpaeq', I load the first module with the command:

pactl load-module module-equalizer-sink


and I'm back 31. Then I upload the second:

pactl load-module module-dbus-protocol


but I get 'Failure: Module initialization failed'

I wanted to clarify, by experience already made, that the equalizer coming from the repository of nilarimogard / webupd8, tends a bit to distort perhaps in preamp the sound. The one integrated into Pulseaudio, no. But it does not yet seem as immediate to be able to dispose of it.

Thanks again for your patience
