<div dir="ltr"><div>Hi,</div><div><br></div><div>I use pulseaudio in a use case where the cpu usage is very high (30%) and IHMO this is not normal.</div>I tried all the tricks to decrease the cpu load without success (resampling-method etc...). The cpu remains high.<br><br>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:<br><br>pactl load-module module-null-sink sink_name=VAC_spk sink_properties=device.description=VAC<br><br>pactl load-module module-remap-source master=VAC_spk.monitor source_name=VAC1_mic source_properties=device.description=VAC<br><br>Everything works perfectly, except the cpu which is 30% for this simple use case.<br>My cpu is a AMD threadripper and i'am with the latest stable release pulseaudio 14.2 freshly compiled, <br>Do you know how to lower the CPU usage?<br><br><div>Thanks</div><font color="#888888"><div><br></div><div>Renaud</div></font></div>
