 Ubuntu 22.04.3 LTS
 I use ffmpeg to record sound from pulseaudio :


 {{{
 ffmpgeio -hide_banner -nostdin -nostats -thread_queue_size 9000
 -use_wallclock_as_timestamps 1 -f pulse -ar 44100 -i recorded.app.monitor
 -acodec flac -ac 1 rec.flac
 }}}


 I use this to stop it :
 {{{
 kill -15 <ffmpeg pid>
 }}}

 This used to work gracefully with no error reported until around 2 month
 ago.

 Now, first **''kill -15 <ffmpeg pid>''** doesn't do anything, even if I
 wait 60 seconds. Nothing new is printed in stdout / log
 After second **''kill -15 <ffmpeg pid>''** these errors are displayed:
