Summary0008275: 'blips' of input signal appear at output when locating
DescriptionUsing 'P' to locate the playhead allows a brief blip of the channel input signal to pass through, even when ardour is set to 'record monitoring handled by audio hardware'.
Steps To Reproduce* set 'Record monitoring handled by:' to 'audio hardware'
* create a new session
* add 1 mono track, routed to master bus
* connect hardware input 1 to audio track
* record a region on the track (to create start & end markers)
* delete the region
* feed a signal into the hardware input
* locate the playhead to different points in the session by pointing with the mouse and pressing 'P'
* on every locate a short 'blip' of the input signal can be heard from the output of the master bus

Is "Session > Properties > Monitoring > Track Input Monitoring automatically follows transport state ("auto-input")" enabled?
and Preferences > Signal Fow > Auto Input does 'talkback' ?

"Auto Input" is on
"Auto Input does 'talkback'" is off
"Session > Properties > Monitoring > Track Input Monitoring automatically follows transport state ("auto-input")" is on

Have reproduced with ALSA backend too. 'Auto Input' doesn't make any difference.
