In the latest version of kdenlive, my sound is not recorded.

In the latest version 24.08.3 of kdenlive, my sound is not recorded.
Something needs to be set up when audio recording worked in the previous version.
When I start and then stop recording, it gives me a message that it wants to transcode the clip and offers me Lossy x264…(VAAPI GPU) but nothing happens after transcoding.
This is happening on Ubuntu 20.04.6 LTS.
