Lower Pipewire CPU usage on Ubuntu while using Firefox
I was noticing high CPU usage for the pipewire process on Ubunutu.
After some digging, I came across this thread. The culprit is an accessibility feature in Firefox. If you are not using firefox’s speech synthases features you can disable it to drop CPU usage.
- Type
about:config
into the Address bar. - Search
media.webspeech.synth.enabled
- Set
media.webspeech.synth.enabled
to false. - Restart Firefox and check pipwire process cpu usage
