If you think 200mV is whopping, I'm seeing a change from 0V to 2V 10s after I close squeezelite (player app), but this into a multimeter from a bare plug without headphones connected. If this was real it would produce a massive pop in the headphones, but all I hear is a faint one. I'll have to solder up a test cable to see what happens with headphones connected, but I suspect the output is going into a high impedance 'off' mode to save power, and can't put significant current into the headphones. I should probably have a look at the A64 datasheet...
