After upgrade to 20.04, sound recording does not work.

Same for me.

I tried with 2 computers (self made computer and Dell Inspiron Core i7).

I'm not sure than it happened when I upgraded to ubuntu 20.04 (worked fine with 19.10) but since yesterday, no speaker and unknown microphone.

same here too

I am getting exactly the same thing.
As reported, it happened when I upgraded to 20.04
It now does not record from speakers or microphone.
Using a Lenovo T480 laptop

same here too
no speaker and unknown microphone

Exactly the same here, other audio recording seems to work fine after the upgrade (zoom in particular). I've attached the output of a "pactl list" command and a screenshot just in case that helps.

Some errors when launching it in a terminal, if it can help :

WARNING Kazam - Failed to correctly detect operating system.

/usr/lib/python3/dist-packages/kazam/app.py:145: Warning: value "((GtkIconSize) 32)" of type 'GtkIconSize' is invalid or out of range for property 'icon-size' of type 'GtkIconSize'

When opening preferences :

Traceback (most recent call last):

IndexError: list index out of range

The code in pulseaudio.py call time.clock() func. But it deprecated from Python v3.3 - https://docs.python.org/3.7/library/time.html#time.clock

All time.clock() calls must be replaced with time.perf_counter() - https://docs.python.org/3.7/library/time.html#time.perf_counter

Worked version for Python 3.8 of the pulseaudio.py file in attach

Patch

Thanks for the patch, it will save my time !

Does anyone know when this patch might be applied? Things are getting critical for me here.

Thank you so much!
Upgrade to Ubuntu 20.04 broke mic in Kazam just when I desperately needed it.
Replacing /usr/lib/python3/dist-packages/kazam/pulseaudio/pulseaudio.py
with version in #8 fixed it for me.

pulseaudio.py和pulseaudio.py.diff复制到下的文件

/usr/lib/python3/dist-packages/kazam/pulseaudio

I clean install ubuntu-20.04,
then install kazam using apt command.

sudo apt -y install kazam

kazam 1.4.5-3 install successfully,
but file -> preferences operation, then crushed.
I send crush report.

Also on Ubuntu 20.10 - file -> preferences -> crash
I have a .crash file but problem not sent.
Attached my .crash file

Also on Ubuntu 20.10 - file -> preferences -> crash

Patch from post #8 applied on Ubuntu 20.04 and 20.10: WORKS FINE
