In the latest days I have encountered another problem. Due to the "auto resume playback" bug I usually pause symfonie without closing it, in order to hold the position of my audiobook. This resulted in a severe battery drain because symfonie keeps the stream open, and pulseaudio doesn't go idle:

I think that after some time that symfonie is in pause, it should stop the stream in order to allow pulseaudio to go idle: a paused player should not consume cpu.
