Bug Description

Upgraded to the base Ubuntu 20.04 (from Ubuntu 19.10). Prior to upgrade, I was able to record either from the Laptops speakers/mic or my Jabra headset/mic. Now, under Preferences, I see nothing for Speaker and "Unknown" for microphone.

I am using an older Dell Latitude Core i5 laptop.

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.

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.

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.

The code in call time.clock() func. But it deprecated from Python v3.3 -

All time.clock() calls must be replaced with time.perf_counter() -

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/
with version in #8 fixed it for me.

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
