I was noticing high CPU usage for the pipewire process on Ubunutu.
|
||
|
|
|
||
|
|
After some digging, I came across [this thread](https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/1968). 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.

|
|
|
||
|
|
1. Type `about:config` into the Address bar.
|
||
|
|
1. Search `media.webspeech.synth.enabled`
|
||
|
|
1. Set `media.webspeech.synth.enabled` to false.
|
||
|
|
1. Restart Firefox and check pipwire process cpu usage
