[pulseaudio-discuss] Virtual audio cable - high cpu usage

I use pulseaudio in a use case where the cpu usage is very high (30%) and
IHMO this is not normal.
I tried all the tricks to decrease the cpu load without success
(resampling-method etc...). The cpu remains high.
My use case is simple. I redirect the sound output of an application to the
sound input of another application (in this case ffmpeg). I load two
modules to create my virtual audio cable like this:
pactl load-module module-null-sink sink_name=VAC_spk
pactl load-module module-remap-source master=VAC_spk.monitor
Everything works perfectly, except the cpu which is 30% for this simple use
My cpu is a AMD threadripper and i'am with the latest stable release
pulseaudio 14.2 freshly compiled,
Do you know how to lower the CPU usage?
