"Bang" when playback starts

Hello there.
I use Ardour 3.5.14. And each time, when I start playback, it sounds like “bang”.
It does not depend on the audio device which is connected to jack.
Here is sample: https://dl.dropboxusercontent.com/u/15829218/ppp.wav
But when editing, it sounds much louder.

I dont hear anything apart from silence

wait, my speakers had been turned down without me knowing.

I have no idea why ardour would be doing that, ive never experienced anything like that in any version of ardour

Wow, I found problem - all TAP plugins produce this sound. Just remove them.

I had the same problem with the convolution plugin from x42-plugins.

how about try the setting “silence plugins when transport is stopped” and see if that helps
