Linux audio stuttering when opening separate application, how to prioritise audio when using Linux?

Spotify, freetube, youtube website, either it's a streaming issue or an audio playback issue. Whenever my cpu is working too hard audio playback stutters and delays making it unlistenable. Actually some games have alright audio so I think it's a streaming issue. Anyway I want to know how to prioritise sound streaming or playback cpu in linux?
