If you didn’t have a look at Call recording succeeds only on first record (Xperia X only, AFAIK), then you probably should. There are some contributions from other OPs that might be relevant.
I have a desktop file (/usr/share/applications/kpa.desktop) where I have:
[Desktop Entry]
Type=Application
X-Nemo-Application-Type=no-invoker
Name=Kill Pulseaudio
Icon=pulseaudio_icon
Exec=killall -15 pulseaudio
Beware, do not kill too fast too often.
