Public bug reported:
After upgrading Carbon X1 gen 9 to Ubuntu 22.04 (from 20.04), there
appeared strange problem with speaker sound in video conferences (Zoom)
and also with Chrome (for example YouTube & Preply).
The problem is as following: the speaker sound level is reduced when
somebody speaks after a gap of silence, then the sound level is quickly
increased to normal level. This creates the very strange fluctuating
up/down sound level which when sound level is low at the start of each
sentence.
This problem was not there with Ubuntu 20.04 on the same laptop. This
problem is also not presented when using Zoom with Windows 11 on the
same machine.
Thank you for your consideration.
Best regards, Rustem
