That may be related to ALSA, specifically, the DMIX. By default, the
DMIX uses 48KHz sample rates and some applications that use lower
rates will have to resample the sound, which leads to he
aforementioned high CPU usage.

You can try either configuring your applications to use 48KHz sample
rates or modify your $HOME/.asoundrc so the DMIX uses a lower rate
such as 44KHz, like this:

pcm.swmixer {
    type dmix
     slave {
        pcm "hw:0,0"
         rate 44100
    }
}

The ALSA wiki has some more details, have a look at
