high cpu usage (by pulseaudio process(es)) only when wazapp is on, yes. went back on 1509, because I'm bit tired of constantly checking the consumption... as soon as I've went back on 1509 the idle consumption is at normal level (16mA), and only this one pulseaudio process (my mistake - this output You've asked me to write is when 1509 was on)... each time I go on 1909, 2009 or 2109 idle consumption goes 35mA (restarting wazapp or rebooting helps for a while), and each time I go back to 1509 consumption normalises at 12-18mA - it's got to be due to something new implemented in 1909 version of Wazapp and on... I suspect those notification sound settings...
